"An' they haven't invented a spell our Hermione can' do."
—A statement regarding Hermione's magical talent[src]
Hermione proved to be an extremely powerful, intelligent and talented young witch. Even before she began her education at Hogwarts, she practised some simple spells which all worked.[21] Remus Lupin claimed that Hermione was the cleverest witch of her age he had ever met.[15] The British witch's magical capability easily surpassed almost every single student in her year, challenged only by a select few. Hermione was considered a "borderline genius"[32] and was the most talented witch in her year at Hogwarts.

"One of my best friends is Muggle-born, and she's the best in our year."
—Harry Potter addressing Hermione's magical aptitude[src]
Magical aptitude: At Hogwarts, Hermione was usually the first to master any spell, and was capable of using spells beyond her educational level.[22] She earned ten O.W.L.s; nine 'Outstandings', and one 'Exceeds Expectations', in Defence Against the Dark Arts. Harry Potter was the strongest student in that subject, but even Harry acknowledged that Hermione was "the best in our year," and repeatedly admired her spell work. She mentioned in her fifth year that the Sorting Hat considered placing her in Ravenclaw, but in the end decided on Sorting her into Gryffindor.[25]
Non-verbal and wandless magic: Hermione became highly skilled at non-verbal magic in her sixth year, being the first to succeed at it in her Defence Against the Dark Arts class and quickly becoming so good at non-verbal incantations that she did not need to say the words aloud for a wide variety of spells.[25] Hermione was known to have practised wandless magic in her years at Hogwarts. She did not need the aid of a wand or magical instrument for a wide variety of spells.[25]
"You're a little scary sometimes, you know that. Brilliant. But scary."

Duelling: Hermione demonstrated her fighting ability on numerous occasions, showing remarkable duelling skill for her age. Although she was incapacitated relatively early in the Battle of the Department of Mysteries, Hermione removed two Death Eaters from the fight in that short time.[22] By the time she accompanied Ron and Harry on the search for the Horcruxes, her spell-work was swifter than opponents such as Mundungus Fletcher and at least two Death Eaters. She defeated Antonin Dolohov and Gregory Goyle, defended Harry from Nagini, repelled Yaxley when he forcibly Disapparated with her, and blasted Fenrir Greyback away from an injured Lavender Brown. She also saved Harry twice in the Horcrux hunt, In which she blasted Nagini away from him and also when she saved him and Ron from being apprehended by Death Eaters when the Trio went to see Xenophilius Lovegood. She defeated many Death Eaters during the Battle of Hogwarts and also held her own against Bellatrix Lestrange with the assistance of Ginny Weasley and Luna Lovegood although Bellatrix's powers proved to be too strong to overcome even for the three of them. Hermione also had very fast reflexes when it came to wand work; for instance, she drew her wand and placed a Shield Charm between Harry and Ron when they were quarrelling before either of them could even draw their wands in 1997, and when the trio was spotted by Death Eaters during the Battle of Hogwarts, she was the first to react, sending them to safety.[6] Hermione was also able to magically manipulate objects around herself to incapacitate or evade others.[16] Her duelling style was creative and unpredictable, mixing non-combat spells along with more conventional combative spells to overcome her opponents.

Defence Against the Dark Arts: Hermione was skilled in this subject as she was able to achieve an 'Exceeds Expectations' in her O.W.L. In their first year she mastered Body-Bind Curse. In their third year when she took Professor Lupin's exam, Harry saw that she did everything perfectly except for the part of fighting the Boggart. Hermione mastered all the spells taught by Harry in their fifth year in Dumbledore's Army. She mastered the Stunning Spell, Impediment Jinx, and various other jinxes and hexes. She was capable of using powerful spells such as the Blasting Curse. Despite this aptitude, this was the one subject Harry Potter was better than her at, something she freely acknowledged. If Hermione became an Auror she would have excelled but instead dedicated herself to rebuilding the wizard laws. Alongside this, in one alternative universe created by Scorpius and Albus' time-travelling experiences, Hermione in fact becomes professor of Defence Against the Dark Arts, although she was notably less pleasant as a person than she was in the 'prime' timeline.
Harry Potter: "It's better we wipe their memories."
Ronald Weasley: "You're the boss. Hermione...you're the best at spells."

Hermione being the first in her class to master the Levitation Charm

Charms: Until she began studying Arithmancy in her third year, Hermione's favourite subject was Charms, and indeed some of her most impressive magical feats were charms. She not only achieved an 'Outstanding' O.W.L. but also received a hundred and twelve percent in her first year Charms exam. Her array of protective charms defended her, Harry, and Ron for almost a year while they were searching for Voldemort's Horcruxes, while several far more experienced wizards were captured within months. She also enchanted her small handbag with an Undetectable Extension Charm to allow her to carry more items in the bag than physically allowed, which allowed her, Harry and Ron to survive the months spent out in the open. Hermione managed to cast the Memory Charm successfully multiple times after having only read the theory behind it[6] and her Memory Charms on Antonin Dolohov and Thorfinn Rowle held even when they were subjected to the Cruciatus Curse.[33] Hermione had a wide knowledge and talent for the powerful shield charms she casted outside their tent each day while hunting for horcruxes. However, the one charm she had trouble with was the Patronus Charm, something Harry noted when she tried casting it when he, Hermione and Ron infiltrated the Ministry of Magic perhaps indicating that although she was skilled with the charm, it did not come as easily to her as most other spells as she perhaps lacked the self-confidence. That said, she learned how to cast the corporeal Patronus Charm in her fifth year and was the first to master the advanced spell in Dumbledore's Army under Harry's tutelage, hers taking the form of an otter.[22] Hermione was noted to have a speciality in creating portable, waterproof fires. In her first year, Hermione used these fires, kept in a jar, to keep the trio warm during winter, and also used it to distract Severus Snape, whom she thought was jinxing Harry Potter's broom during his first Quidditch match. These flames were used again in Moaning Myrtle's bathroom to light the cauldron above one of the toilets while Polyjuice Potion was brewed in her second year so that Harry Potter and Ronald Weasley could interrogate Draco Malfoy about the Heir of Slytherin. During her sixth year, Hermione successfully cast the Confundus Charm on Cormac Mcklaggen. Hermione mentioned in 1997 that she had been practising how to use her Patronus for messaging,[6] but it is unknown if she ever actually carried this out.

Potions: Hermione was able to brew the very advanced and difficult Polyjuice Potion, by the time she was in second year for her, Harry, and Ron to find the truth about the Chamber of Secrets from Draco Malfoy by disguising themselves as his friends.[23] She achieved an 'Outstanding' on her Potions O.W.L. and was only one of twelve to advance to N.E.W.T.-level. She was able to identify potions and their effects quickly after having only read about them. She was the only one in her sixth year class who understood Golpalott's Third Law, without need for further explanation and was able to compose an antidote containing fifty-two ingredients, including a chunk of her own hair. The only time she was ever out-smarted in potions was in her sixth year by Harry Potter because of using Half-Blood Prince's old copy of the Advanced Potion-Making textbook that was full of hints and scribbles which helped Harry excel.[25]
"Only Hermione Granger had made any difference to her match; Professor McGonagall showed the class how it had gone all silver and pointy..."
—Hermione's achievement during her first Transfiguration lesson[src]
Transfiguration: Hermione seemed to be particularly talented at Transfiguration. She was the first in her class to succeed at transfiguring a match into a needle in their first lesson, long before any other student[21] and earned an 'Outstanding' in her O.W.L. exam. In 1994 she was the only one able to transform a Hedgehog to pincushion. She could also vanish objects, which is one of the hardest spells taught at Ordinary Wizarding Level. In 1995 she was able to vanish Harry Potter's potion after believing him to be finished with it and a kitten by mid-year the hardest vanishment challenge of all. Hermione was very skilled at conjuration, an advanced type of transfiguration; for example, in her sixth year, she was able to conjure a flock of canaries,[25] and by the next year, she could conjure a wreath of flowers and a flask non-verbally. She could also perform Human Transfiguration, which is noted to be very difficult and did so in 1998 to disguise Ron during the break-in at Gringotts Bank.
Dark charms: Hermione was not known for her ability to cast Dark magic and the extent of her ability within this magical discipline is truly unknown (however, one would assume given her borderline genius status that she was no slouch). Still, she must have had some ability as she was able to come up with a very sophisticated jinx that would deform the face of a person who betrayed the D.A.. She was also able to successfully cast a Stinging Hex at a moment's notice. In her fourth year she was also able to cast the Leg-Locker Curse in her first year and the Jelly-Legs Jinx in her sixth.
Apparition: Hermione was the first in her class to Apparate successfully as she had achieved Apparition twice in that time and passed her test on the first attempt. According to Ron, her performance was "perfect" and the instructor praised her talent greatly.[25] While on the hunt for the Horcruxes with Harry and Ron, Hermione frequently Apparated and Disapparated the three of them using side-along Apparition, twice when they were falling through the air.[6]
Study of Ancient Runes: Hermione was gifted in translating ancient runes into English. She earned an 'Outstanding' O.W.L. in the subject and took it to N.E.W.T.-level. This is what later helped lead her, Harry Potter, and Ronald Weasley to the Deathly Hallows. She later translated the original copy of The Tales of Beedle the Bard into English, which she published sometime before working at the British Ministry of Magic.
Herbology: Hermione earned an 'Outstanding' O.W.L. in this subject, thus showing she has great talent in this field as well. She was particularly skilled in spells related to magical plants. In her first year, she saved Harry and Ron from some Devil's Snare in the Underground Chambers by conjuring Bluebell Flames. She also had knowledge of various different plants; for example, in her second year, she was the only one who knew what the Mandrake root was and what it did.
Arithmancy: This was Hermione's favourite subject and, considering she was one of the few people to take this subject, she must have skill in this field, too. She earned an 'Outstanding' O.W.L and took the subject to N.E.W.T.-level.
Logical thinking and intelligence: Hermione had a mastery of logic that most wizards lacked, as she stated that "a lot of the greatest wizards haven't got an ounce of logic". In 1992, Hermione was able to use logic to get Harry Potter past a protective measure that was taken to protect the Philosopher's Stone by Severus Snape. Hermione was noted to be a "borderline genius",[32] getting top scores in every class, and getting 'Outstanding' in all her O.W.L.s except Defence Against the Dark Arts. She often provided the trio with vital information when carrying out research into the various mysteries they faced. For example, she was the one to figure out through research that the monster in the Chamber of Secrets was a Basilisk and in her third that Professor Lupin was a werewolf. However, her intelligence could be a handicap. She tended to rely more heavily on facts and information that could be proven by background analysis rather than making intuitive leaps. Harry was generally the one to put the pieces together to create the final picture necessary to explain recent events and willing to make assumptions where Hermione disproved ideas if there was no clear evidence for them.
Muggle Studies (knowledge): This was one of the subjects Hermione chose to take in her third year with the aid of a Time-Turner but dropped the subject after a year, as Hermione was a Muggle-born witch and so knew a great deal about Muggles already. She was seemingly good at it because she could bring another point of view to the classroom and the lessons. She achieved a score of over 300% on her final exam in third year.
Astronomy: Hermione was known to have gained an 'Outstanding' O.W.L. in this subject, but she decided not to continue with it at N.E.W.T.-level. She often helped Harry Potter and Ron Weasley do their homework as they often didn't remember the required facts.
History of Magic: Hermione was very interested in the history of the wizarding world from a young age. Even before starting at Hogwarts, she bought several books and learned them by heart, including Hogwarts: A History. She was one of very few students who payed attention to Professor Binns' lectures. She earned an 'Outstanding' O.W.L. in the subject, which was hard to do, considering how boring the class was said to be. She was also known to take excellent notes in the class.
Care of Magical Creatures: Hermione earned an 'Outstanding' O.W.L. in Care of Magical Creatures. She had no problem interacting with Buckbeak in her third year, but stated in her sixth that he scared her. Her skills with interacting with animals were also demonstrated with her views on house-elves and her work on S.P.E.W.. She interacted well with house-elves like Dobby and Winky and it was Hermione who encouraged Harry to treat Kreacher more kindly after he inherited him. These skills allowed her to join the Department for the Regulation and Control of Magical Creatures where she continued her work with S.P.E.W., working for the rights of both house-elves and other underprivileged non-humans.
Healing magic: Hermione had some basic skills with Healing Magic. She had knowledge of Mandrake's Healing properties in her second year, and was able to take care of both Harry Potter's wound from fighting Nagini and Ron Weasley's splinching wound in 1997.
Alchemy (theory): Hermione had read a book containing information on Alchemy and the Philosopher's Stone in her first year. In her sixth year, she easily understood Golpalott's Third law.
Quidditch (theory): Although she wasn't very interested in it, Hermione had some theoretical knowledge of Quidditch and Quidditch balls. She had read Quidditch through the Ages in her first year, and also knew about the Snitches' flesh memories, something of which Quidditch players Harry Potter and Ronald Weasley did not.
Leadership skills: While Harry did the majority of leading among the trio, it was usually Hermione who kept him on track when he, Ron and Hermione had a task to do, and she sometimes did the same with Ron, demonstrating good leadership skills. Hermione also helped form and co lead Dumbledore's Army alongside Harry and Ron, and her leadership skills were again demonstrated when she joined the Ministry, as she helped improve the rights of House Elves and other underprivileged magical creatures in the Department for the Regulation and Control of Magical Creatures, and then got promoted to Deputy Head of the Department of Magical Law Enforcement, in which she helped eradicate the old laws which only favoured pure bloods. She was eventually promoted to the post of Minister for Magic before 2019, which again demonstrated her good leadership skills, despite not desiring high positions and only leading when she was forced to do so and when the time was right.
Possessions

Hermione's first wand

Vinewood wand: Hermione purchased a 10¾" vine wood wand with a dragon heartstring core in 1991. There is a pattern of vines the whole way up the wands handle. She used it until the spring of 1998, when she, Harry Potter, and Ron Weasley were captured by Snatchers, who confiscated their wands. She subsequently used Bellatrix Lestrange's wand.
Revealer: Hermione owns a Revealer, which renders invisible ink visible. She tried to use it on Tom Riddle's diary but no ink showed up.[34] It is unknown if she still had it in her possession after 1992.
Crookshanks3
Crookshanks

Crookshanks: Hermione obtained a ginger part-Kneazle cat Crookshanks, in 1993. Crookshanks is highly intelligent, but was not fond of many people besides Hermione.[15] It is unknown what happened to Crookshanks after Hermione left him at the Burrow in the summer of 1997 in order to locate and destroy Lord Voldemort's Horcruxes.[6] It's very likely the two were reunited seeing their strong affection for one another.
Time-Turner: In 1993, just before her third year at Hogwarts, Hermione obtained a Time-Turner from the Ministry of Magic in order to facilitate her attending more classes. She also used it, at the end of the school year, to save Sirius Black and Buckbeak, along with Harry Potter. Afterwards, Hermione returned the Time-Turner, returning to a normal class schedule.[15]
Charmed handbag: Hermione had a small, beaded handbag on which she placed an Undetectable Extension Charm in the summer of 1997. She used the handbag to carry supplies such as clothing, books, Dittany, and camping equipment on her, Harry, and Ron's quest to locate and destroy Voldemort's Horcruxes.[6] The bag was small enough to fit in her sock, so as to not have it stolen during the Skirmish at Malfoy Manor.
Tales of Beedle the Bard
The Tales of Beedle the Bard

The Tales of Beedle the Bard : Albus Dumbledore bequeathed the original publication of The Tales of Beedle the Bard , written in runes, to Hermione. It contained a clue about the Deathly Hallows which led Hermione, Harry, and Ron to Xenophilius Lovegood, who told them about the legendary items.[6] Later in life, Hermione translated the book into English and published her translation.
Bellatrix Lestrange's wand: In 1998, after the Skirmish at Malfoy Manor, Hermione lost her own wand while Ron Disarmed Bellatrix Lestrange. Harry grabbed Bellatrix's wand as they left, and Hermione subsequently used it, though it did not work well for her, as she did not win its allegiance. Hermione used this wand at least until the Battle of Hogwarts, when she fought Bellatrix with her own wand.[6]

Advanced Rune Translation: Hermione owned a copy of this book, probably because it may have been required for her lessons in 6th year Ancient Runes which she started in her 3rd year with the aid of a time turner. She was seen to be reading this book before the start of her 6th year, after her trip to Diagon Alley.
Ancient Runes Made Easy: The book was on a beginners' level for Ancient Runes Hermione was seen reading it in her second year when she was thinking about taking Ancient Runes for a subject in the following next year. She probably used the book in her third year when she took the subject.
An Appraisal of Magical Education in Europe: This book is about magical schools in Europe. Prior to 1994, Hermione had read it and learned of many things, including the Durmstrang Institute's reputation for having an emphasis on Dark Magic. It is also mentioned to have information about Beauxbatons Academy of Magic. Later, in 1997, Hermione considered taking this book with her as she was sorting supplies for their mission to find Voldemort's Horcruxes. It is not specified if it was one of the books she decided to bring with her when she left with Harry and Ron. It is, however, unlikely as it was of no real use to them on their mission.
Aqua Eructo spellbook: The copy which belonged to Hermione was originally the possession of Barty Crouch Jr. who, at the time, was disguised as Professor Moody. Hermione, Harry and Ron used the book to perform the spell; Aqua Eructo, which proved helpful in defeating the Salamander kept in the Professor's rooms.

Dress robes: Hermione wore a set of dress robes to the Yule Ball in 1994. They were made of a "floaty, periwinkle-blue material" and were considered to be quite attractive. In 1997, Hermione, once again, wore dress robes to the Wedding of William Weasley and Fleur Delacour. They were lilac in colour and had matching shoes.
Dumbledore's Army coin: The Dumbledore's Army coin was a fake Galleon created by Hermione in 1995 to inform members of Dumbledore's Army when the next meeting would take place. She used it a great deal and ensured that her spellwork was good enough to disguise the information as typical text on a Galleon.
Earrings
Hermione's Yule Ball earrings

Yule Ball earrings: These were worn by Hermione to the Yule Ball in 1994; her fourth year, which she attended with Viktor Krum, one of the four Champions in the Triwizard Tournament at Hogwarts.
Expelliarmus spellbook: This spellbook is a book that contained information on the Disarming Charm. It also contained the instructions on how to perform the spell. Hermione eventually persuaded Harry Potter and Ron Weasley to learn the spell after a confrontation with Draco Malfoy.
Gilderoy Lockhart's card to Hermione Granger: This letter was written by Gilderoy Lockhart to Hermione in 1993, expressing his get-well wishes. Hermione hid it under her pillow in the Hospital Wing until her friends Harry Potter and Ron Weasley discovered it.
Great Wizarding Events of the Twentieth Century: This books is about prominent events in the wizarding world during the twentieth century. Harry Potter is mentioned in this book, which Hermione read before meeting him in person in 1991.
Herbivicus spellbook: The spellbook is a book containing information on how to perform the spell; Herbivicus. The first copy mentioned was owned by Professor Pomona Sprout, who kept it in one of the gardens of the Hogwarts greenhouses at Hogwarts Castle. Harry Potter, Ronald Weasley, and Hermione later came across it during the 1994–1995 school year and used it to learn the spell, which proved valuable against the plants that have not fully grown which can be found all over the Hogwarts grounds. Hermione later, either purchased a copy for herself, or took the Professor's.

The Life and Lies of Albus Dumbledore

A copy of The Life and Lies of Albus Dumbledore: Hermione Granger had a copy of this book in her possession after her visit with Harry to Godric's Hollow and their run in with Nagini disguised as Bathilda Bagshot. She picked it up as the two left the house and she read it while running and camping during her seventh year with Harry and Ron, attempting to find clues which would help her and her friends locate and destroy Voldemort's Horcruxes. Given her animosity towards the author, Rita Skeeter, it is highly unlikely that she kept it following the Second Wizarding War.
Red-jewel necklace: This necklace was worn by Hermione to the wedding of Bill Weasley and Fleur Delacour in 1997. She wore it up until she ran away from the wedding after it was attacked by Death Eaters. It was later destroyed by Scabior when she, Harry and Ron were taken to Malfoy Manor.
Pencil case: She had a large pencil case which allowed her to keep all her quill and other writing equipment together. She is first noted to have had it in her sixth year when an argument with Ron Weasley made her wipe her wet eyes on it. It is, however, highly possible that she owned this object since her first year and had not replaced it since.
A scarf: Hermione owned a dark purple/red scarf and wore it frequently in 1997 whilst on the run with Harry Potter and Ron Weasley during the Second Wizarding War. She left it behind on their travels during her seventh year and it was later picked up by Scabior.
Hogwarts a History
Hogwarts: A History (Hermione's favourite book)

A copy of Hogwarts: A History: Hermione Granger often referred to this book on many things concerning Hogwarts School of Witchcraft and Wizardry. It was her favourite book and she would often read it in her free time. Three of the main topics brought up in it talk about Apparition within the castle, muggle electronics and the ceiling in the Great Hall.
A watch: This watch was worn and used by Hermione Granger in her youth at Hogwarts. She was seen to be wearing it during her third and fourth year.
A copy of Magical Hieroglyphs and Logograms: This book is about magical theory. Hermione used this reference book over breakfast one morning, in conjunction with a pile of other books, to work on her Ancient Runes homework.

Hermione: "Well, to tell you the truth, skiing's not really my thing. So I've come for Christmas... Anyway, Mum and Dad are a bit disappointed, but I've told them that everyone who's serious about the exams is staying at Hogwarts to study. They want me to do well, they'll understand."

Mr and Mrs Granger were Muggle dentists who seemed proud of their witch daughter. They appeared to be accepting of the wizarding world, as they went shopping with Hermione in Diagon Alley and allowed her to spend several holidays with the Weasley family,[23] but did not approve of their daughter using magic as a quick-fix, as indicated by their not allowing Hermione to magically fix her teeth.[24] They correspond by owl post with their daughter throughout the school year,[22] but other than one holiday in France with her parents, Hermione spent almost all of her time in the wizarding world. In 1995, she planned to go skiing with them during the Christmas holidays, but ended up going to 12 Grimmauld Place to try to cheer Harry up instead. Hermione told her parents that the reason for her cancelling was to study for exams, indicating that her parents expected her to do well in school and were probably not aware of the extent of their daughter's involvement in activities relating to the Second Wizarding War.[22]

—Hermione on her parents' memory modification[src]
To protect them during the height of the war, Hermione modified her parents' memories in 1997 to make them believe they were entirely different people, and they left the country.[6] After the war, she found them in Australia and restored their memories.

Harry Potter, her best friend and future brother-in-law

Hermione became friends with Harry Potter after they as well as Ron Weasley took down a Mountain Troll together in their first year.[21] They tend to get along very well on a day-to-day basis, though Harry occasionally becomes annoyed by Hermione's nagging, while she occasionally becomes annoyed by his lack of discipline and conviction in his schoolwork. Their only notable row was over Hermione getting Harry's Firebolt confiscated in their third year, which she felt it might be a trap. Harry and Ron reconciled with Hermione after Hagrid scolded them for their treatment of her. Harry and Hermione are quite similar in their dour, brooding tendencies in times of trouble, and often need Ron's humour and levity to counterbalance their intense personalities.

Harry, Hermione, and Ron spent nearly all their time together during their years at Hogwarts, and shortly afterwards, Hermione led Harry through time-travel, and together they rescued Sirius Black and Buckbeak; Hermione breaking the rules of using her Time-Turner, something she admitted was incredibly dangerous, demonstrated the strength of her friendship with Harry.[15] The following year, Hermione was the only student who believed Harry when he told her he had not put his name in the Goblet of Fire, and spent much of the Triwizard Tournament teaching Harry useful spells and trying to reconcile him and Ron.[24]

While Harry and Hermione typically row less than Ron and Hermione, they have the most philosophical and moral disagreements with one another. Ron typically defers to Harry's opinions on important decisions, and tends to hold back when Hermione confronts Harry about them, letting them battle it out. For example, Harry and Hermione fight about how best to deal with Dolores Umbridge when she infiltrates Hogwarts, whether or not Sirius's judgement can be trusted, whether or not Harry should try use Occlumency to block out his mental link with Voldemort, whether Dumbledore's past makes him an unworthy leader, and whether they should pursue the Hallows or the Horcruxes. Harry tends to be dismissive of Hermione's opinions, and can even grow angry when she tries to argue her point, but generally realises later that she was right. For example, Harry was often dismissive of Hermione's insistence that all house-elves deserve respect and kindness, and is neglectful towards Kreacher because of his bigotry until finally realising the horrifying nature of his enslavement.

Harry&Hermion poa
Hermione protecting Harry, her willingness to put his best interests first

While Harry tended to have more fun with Ron, Hermione was consistently his place of refuge when others abandoned him, from Ron's jealous withdrawal during the Triwizard Tournament, to Harry's discovery of Dumbledore's past during the war. Despite their differences, Harry and Hermione tended to support one another at the expense of others when necessary. Hermione repeatedly chose to help and support Harry in his fight against Voldemort, regardless of personal cost. Examples include breaking the laws regarding time travel in order to help him save Sirius, teaching him defensive magic in preparation for the Triwizard Tournament, blackmailing Rita Skeeter in order to give him a way to tell the public about Voldemort's return, protecting him from torture by Dolores Umbridge, and Obliviating her parents in order to go on the run with him. She notably chose to support him even when Ron did not. Smaller acts of friendship include helping him with homework and cheering him on at Quidditch games.

Harry is similarly protective and supportive of Hermione. Much like Hermione, Harry is often a place of refuge for Hermione when others leave her. More so than Ron, Harry understands Hermione's emotional feelings and is compassionate towards her. Harry often comforts Hermione and shows her kindness and care when she is upset. On the occasion that Buckbeak the Hippogriff is executed, Harry consoles her as she cries.

He is also quick to defend Hermione from Cho Chang, Draco Malfoy, and others who insult her for her looks or parentage, and shows his pride in her intellect on numerous occasions. He consistently praises her intelligence and magical skills to teachers, asks her for help in dangerous situations, and defends her against bullies. On one occasion, he even chooses to side with her over Ron, supporting her when Ron begins a relationship with Lavender Brown.

Harry also defends Hermione physically on instinct. This shows his willingness to put her before himself as well as his unconditional brotherly love for her. For example, when Lupin turns into a werewolf and attacks Hermione and Harry, Harry shields her from the danger.

Harry and Hermione having a very intense and charged moment

Many people, including Ron, Cho Chang, Viktor, Krum, Mrs Weasley, and Professor Dumbledore, have occasionally mistaken Harry and Hermione's relationship to be a romantic one, given their closeness and expressions of physical affection, such as kisses on the cheek, staying by one another's bedsides when hurt or injured, embracing each other, and holding hands.[24][35] Harry eventually explains to Ron that he and Hermione are like brother and sister.[6] They share similar upbringings as only children raised in the Muggle world, and show each other unconditional love despite many differences and disagreements. During their time alone during the war, Hermione and Harry experienced some "charged moments," and "shared something very intense" of which no one else was a part of, however, their relationship ultimately remained platonic.[36]

Hermione and Harry remained best friends into adulthood, and eventually became siblings in-law when Hermione married Ron Weasley and Harry married Ginny Weasley. Hermione was also the aunt and godmother of Harry's three children: James Sirius, Albus Severus and Lily Luna. They were also coworkers for many years as employees of the Ministry of Magic in law enforcement.

It is interesting to note that Albus Dumbledore's final plan to defeat Lord Voldemort, in which Harry would learn the story of the Deathly Hallows in time to use them against Voldemort, revolved not only around Harry himself, but Hermione as well. Dumbledore knew that Harry was too passionate and angry to be able to keep from attempting to become Master of Death, and so entrusted The Tales of Beedle the Bard to Hermione, so that she would learn of the Hallows' symbol first and would be able to caution and guide Harry down the path of reason.

Ron Weasley
"Oh, maybe she and Ron will be alright with a bit of counselling, you know. I wonder what happens at wizard marriage counselling? They'll probably be fine. He needs to work on his self-esteem issues and she needs to work on being a little less critical."
—J. K. Rowling on Hermione and Ron's adult relationship[src]
Ron Weasley
Ron Weasley, the love of her life and father to her children

Ronald Weasley was, essentially, the love of Hermione's life. Although their relationship would have many ups and downs, Hermione and Ron Weasley were good friends for most of their years at Hogwarts, and of course, were best friends with Harry Potter, who was usually a mediator in their disputes. They tended to argue frequently, though they usually got over their arguments, which tended to be minor or about trivial issues, although there were a few times when it seemed as if their friendship would be irreparable. As they grew older and matured, Ron and Hermione tended to fight less often and become more in touch with their feelings for each other. Hermione sometimes had the tendency of calling Ron "Ronald". Their first major falling-out was in their third year, when Ron accused Hermione's pet cat Crookshanks of eating his pet rat Scabbers.[15]

Hints of her feelings for Ron were shown as early as their first year, when she was badly hurt emotionally when he made fun of her for not having friends due to her bookish and bossy nature. Accoridng to Neville she spent the whole afternoon crying in the loo before the incident with the troll took place. In their third year Ron saw Sirius Black standing over him with a knife, Hermione was shocked and scared the most and even cried. They were both very awkward and embarrassed at times, being insecure with their own feelings for each other, and Ron was frequently jealous that Harry and Hermione liked each other. Ron was used to always being in Harry's shadow and did not want the girl he loved to be also taken from him by his best friend. Hermione was greatly offended when Ron initially didn't ask her to the Yule Ball as his partner until he got rejected by Fleur Delacour. When it is revealed Viktor Krum was Hermione's date, a jealous Ron got into a heated row with Hermione, which she ended by making clear that she would go as Ron's date in future if only he asked her as his first choice. Ron and Hermione's relationship again suffered when Ron began dating Lavender Brown in 1996, though the two reconciled after Ron was accidentally poisoned, leaving Hermione shaken. Ron's relationship with Lavender ended soon after, and both he and Hermione were more content for it.[25]

Hints of romantic feelings between the two could be seen as early as their second year, as Ron was particularly protective of Hermione and disgusted by her crush on Gilderoy Lockhart.[23] During the Yule Ball in 1994, Hermione was affronted by Ron's clumsy attempt to ask her to go with him, and Ron was jealous of her attendance with Viktor Krum; this jealousy would persist for years.

In turn, Hermione was jealous of Ron's crush on Fleur Delacour, though expressed it in a subtler way.

In their fifth year, Hermione kissed Ron on the cheek before the Quidditch Tournament, to which he reacted by being "puzzled" and touching the spot where she kissed him. During Gryffindor's Quidditch try-outs in their sixth year, Hermione also Confunded Cormac McLaggen to increase Ron's chances of being made the team's Keeper. Also, Hermione became jealous (but she tried to conceal it) when Ron began dating Lavender Brown and kissing her frequently.

— Hermione and Ron after the latter's return to her and Harry[src]
By the summer of 1997, the two were closer than ever and "sort of" together, according to Harry. They danced together at Bill and Fleur's wedding, and were generally kinder to one another. During the hunt for the Horcruxes, Ron comforted Hermione several times by putting his arm around her, and Harry believed that they might have fallen asleep holding hands. Hermione was extremely upset when Ron temporarily left her and Harry, crying often, and she was absolutely furious with him when he returned. It was also revealed, through a vision caused by the locket Horcrux, that one of Ron's deepest fears was that Hermione preferred Harry to him.

Ron and Hermione's first kiss during the Battle of Hogwarts

The two eventually made up, and Hermione initiated a kiss during the Battle of Hogwarts, when Ron suggested saving the house-elves and not ordering them to fight for wizards. Hermione, who had been a promoter of house-elf rights since her fourth year and even started her own society to help house-elves (the Society for the Promotion of Elfish Welfare) was so delighted at Ron's unexpected display of sensitivity that she kissed him on the lips, something that was met with surprise, eagerness and enthusiasm, but caused the pair to become embarrassed after Harry asked them to "hold it in".

Some people had expected Ron and Hermione to become more than friends much sooner and Harry Potter had even thought that they would start dating in their sixth year. In 1997, when the Trio was captured by Snatchers and brought to Malfoy Manor, Fenrir Greyback mistakenly called Ron Hermione's boyfriend when she tried to protect him. Also, Ron screamed and yelled and was in terrible distress when he heard Hermione being tortured by Bellatrix Lestrange in Malfoy Manor. The pair eventually married and had two children, Rose and Hugo Weasley.[6]

They were rather young when they were married, and their relationship evolved over time. By the time that Hermione was elected Minister For Magic, Ron had become more the stay-at-home-dad due to the convenience it placed on their respective careers, as Ron's entrepreneurial exploits could be more easily conducted than Hermione's careers in law enforcement and eventually politics. Their combative relationship eventually subsided for a more affectionate one, as Ron was seen to kiss Hermione in public extremely often as noted by their nephew, Albus Potter. Hermione was initially wary when Ron spoke of how early they had married and was jokingly suspicious that he wanted a break from their marriage, but was deeply moved when Ron told her that he wanted to renew their vows and marry her all over again after reading about how Muggles occasionally did such a thing. Hermione was so touched by her husband's suggestion that they began to kiss passionately over her mountain of paperwork in her office. This shows how Ron had matured into a startling romantic over the years and how it helped to temper their initially rocky relationship that begun 31 years prior.

Ginny Weasley
Ginny Weasley : "Hermione told me to get on with life, maybe go out with some other people, relax a bit around you, because I never used to be able to talk if you were in the room, remember? And she thought you might take a bit more notice if I was a bit more — myself."
Harry Potter: "Smart girl, that Hermione."

Ginny Weasley, her good friend and future sister-in-law

Ginny Weasley was Hermione's best female friend. The two grew close when Hermione stayed in Ginny's room at the Burrow during her many summertime visits. Ginny was the only one Hermione told about being asked to the Yule Ball by Viktor Krum,[24] while Hermione was the only one who knew that Ginny had been learning to fly in secret for years.[22] She also gave Ginny advice about dealing with her feelings for Harry — advice that eventually led to the two dating,[25] and eventually marrying.

Hermione comforted Ginny after an encounter with Dementors upset her in 1993,[15] and after the death of her brother Fred in 1998.[6] However, Hermione would not have been afraid to stand up to Ginny when she felt that Ginny was wrong. The two remained very close after the war and eventually became sisters-in-law when Hermione married Ron, making her an aunt to Ginny's three children, James, Albus, and Lily, as well as being chosen to be godmother to Ginny's eldest son James, and making Ginny Rose and Hugo's aunt and almost certainly Rose's godmother.

The Weasley family, her future in-laws

Because of her friendships with Ron and Ginny Weasley, Hermione became friendly with the entire Weasley family. She spent a portion of many of her summer holidays at their home of the Burrow, and attended some family outings with them, such as shopping for school supplies in Diagon Alley and attending the 1994 Quidditch World Cup with them. Arthur Weasley was fascinated by the Muggle world and thus Hermione's background, and even invited Hermione's parents for a drink upon first meeting them. Molly Weasley was fond of Hermione, though she treated her coldly for a brief time after Rita Skeeter printed lies about Hermione toying with the hearts of Harry Potter and Viktor Krum, much to Hermione's bewilderment. After Harry explained that the stories were false, Mrs Weasley once again warmed up to Hermione. Also, she and Percy Weasley were considered to be on good terms until their fight over elf rights.

Fred and George Weasley, her friends and future brothers-in-laws

Fred and George Weasley seemed to regard Hermione and Harry almost like other younger siblings, teasing them as well as being protective of them. When Draco Malfoy called Hermione a "Mudblood" in 1992, the twins were outraged, and attempted to attack him.[23] Although Hermione disapproved of some of their antics, trying to use her status as a prefect to keep them in line, she still got on well with them. Hermione once argued with them that the Ageing Potion they planned on using to trick the age line protecting the Goblet of Fire wouldn't work because Dumbledore would have already thought of a foolish ageing potion. They didn't listen and tried to cross the line which resulted in them being thrown back and grow long, white beards.The only time she was notably angry with them was when they tested out their Skiving Snackboxes on unsuspecting first year students; though the twins initially scoffed at her concerns and her ability to make them stop, they backed down when she threatened to tell their mother.

However, Hermione still admired the cleverness and creativity of their spell work,[22] once remarking that they could do some "extraordinary magic," which Fred was flattered enough by to offer Hermione material from their joke shop free of charge.[25] Fred and George also tried to get Hermione to relax, joking around with her about things such as their late uncle Bilius's penchant for making mischief at weddings.[6] Hermione was devastated when Fred was killed during the Battle of Hogwarts. Hermione was not as close to the other Weasley siblings, though she was invited to Bill's wedding to Fleur Delacour in 1997.

With her marriage to Ron, Hermione became a part of the Weasley family herself.

Fleur Delacour
FLEUR1
Fleur Delacour, her future sister-in-law

When Hermione first met Fleur Delacour, an incredibly beautiful, French, part-Veela witch, in 1994, during the Triwizard Tournament. Hermione disliked Fleur almost immediately, as she was given to fussily and loudly criticising nearly everything at Hogwarts, from the weather, to the decoration and food. The fact that Ron had a little bit of a crush on Fleur didn't help, but he eventually got over it.

Hermione, like Ginny and Mrs Weasley, was infuriated by Fleur's arrogance and constant complaining when Bill Weasley sent Fleur, his then fiancée, to the Burrow to get to know his family. However, when Fleur responded to Bill becoming permanently disfigured by Fenrir Greyback with indignant denial that Bill's appearance would in any way effect their marital plans, Hermione most likely set her feelings aside.

Despite seeming rather inconsiderate and self-centred, Fleur proved to be courageous and ultimately caring, even selfless, in her own way. She put her life in danger by posing as one of Harry's decoys in the Battle of the Seven Potters, and after the Battle of Malfoy Manor, Hermione, Harry and Ron, along with Luna Lovegood, Dean Thomas, and an injured Garrick Ollivander and Griphook, stayed with Bill and Fleur for a month at Shell Cottage, where Fleur took care of them all like a mother. Later, Fleur became Hermione's sister-in-law through her marriage to Bill Weasley, and Hermione's marriage to Ron Weasley.

After the Second Wizarding War, Hermione had two children with Ron Weasley: a daughter named Rose and a son named Hugo.

Rose started her first year at Hogwarts in 2017, along with her cousin, Albus. Ron stated that Rose had inherited her mother's brains. Hermione was probably very close to Rose because she was also described as smart, yet not a complete know-it-all.

Hugo was born in 2006 or 2007. He most likely inherited his father's Quidditch skills, as he is noted to fly a lot with his cousins Albus Potter and James Potter. He also appears to have a quiet demeanour.

Nieces and nephews

As four of Ron Weasley's five surviving siblings were married by 2017, Hermione had quite a few nieces and nephews through her husband: Harry and Ginny had three children (James, Albus and Lily), as did Bill and Fleur (Victoire, Dominique and Louis), while George and Angelina Johnson had a son and a daughter (Fred and Roxanne), and Percy Weasley had two daughters (Molly and Lucy) with his wife, Audrey. Victoire Weasley, one of Fleur and Bill's daughters, was seen kissing Teddy Lupin at King's Cross Station, by James Potter, Hermione's nephew and godson. Hermione visited them all on many occasions. It can be assumed that she was closest with Harry's children.

Neville Longbottom, her friend

Hermione was good friends with Neville Longbottom. They met on the train to Hogwarts during their first year and she helped him search for his toad Trevor.[21] Hermione helped Neville many times with their school work, particularly with Potions, as Professor Snape noted that she was often "hissing instructions in his ear."[15] In their fourth year, Hermione noticed Neville's horrified reaction to witnessing the Cruciatus Curse be performed on a spider by Professor Alastor Moody (actually Barty Crouch Jr), and shrieked for the teacher to stop. That same year, Neville asked Hermione to attend the Yule Ball with him, as she had "always been really nice" to him, though she had already agreed to accompany Viktor Krum.[24]

Hermione often fiercely defended Neville when others insulted him, and her friendship and support, as well as that of other D.A. members, likely contributed to Neville gradually gaining self-confidence and courage.[6] Neville was obviously very fond of Hermione, and appreciative of her kindness and all the help she had given him. It was hinted that he spoke of her frequently to his grandmother, Augusta Longbottom, who seemed to already know a good deal about Hermione when they first met at Saint Mungo's in 1995. Following the war, they kept in touch.

Luna Lovegood, a good friend

Although Hermione rarely saw eye-to-eye with Luna Lovegood due to their very different world views and beliefs, the two became very good friends through Dumbledore's Army. Hermione first met Luna on the Hogwarts Express in 1995; she insulted The Quibbler, but backtracked when Luna told her that her father was the editor. Hermione was frustrated with Luna's belief in all manner of things without proof or logical grounds, but eventually simply accepted their differences, telling Luna that her planned trip to Sweden in search of a Crumple-Horned Snorkack sounded "lovely".[22]

The following year, Luna comforted Hermione when she was upset over her fight with Ron.[25] Hermione was one of the five portraits Luna painted — along with Harry, Ron, Ginny, and Neville — and hung from her bedroom ceiling, the word "friends" linking them in gold writing. When Xenophilius Lovegood attempted to turn Harry, Ron, and Hermione over to Death Eaters in exchange for his daughter's safety, Hermione engineered their escape so that the Death Eaters saw Harry briefly, thus ensuring that both Luna and her father were not harmed. Despite disagreeing with Luna on many things herself, Hermione defended her when others insulted her; for example, she tried to kick Ron for teasing Luna about Gurdyroots at the wedding of Bill Weasley and Fleur Delacour, and snapped at the portrait of Phineas Nigellus Black for calling Luna an oddity. The two girls remained close friends in adulthood and saw each other regularly. Luna may be one of the best female friends of Hermione (along with Ginny), as she was only seen with these girls during her school-time at Hogwarts.[6]

Minerva McGonagall
Professor McGonagall: "Potter! Weasley! What are you doing?"
Harry Potter: "Hermione. We haven't seen her for ages, Professor, and we thought we'd sneak into the hospital wing, you know, and tell her the Mandrakes are nearly ready and, er, not to worry."
Professor McGonagall: "Of course. Of course, I realise this has all been hardest on the friends of those who have been… I quite understand. Yes, Potter, of course you may visit Miss Granger, I will inform Professor Binns where you've gone. Tell Madam Pomfrey I have given you permission."
— Professor Minerva McGonagall softening when Harry and Ron tell her they want to visit Hermione[src]

Minerva McGonagall, her Head of House and professor

Professor Minerva McGonagall took a shine to Hermione from the first class she had with her, granting the first-year student in her house one of her "rare smiles" when Hermione successfully transfigured a match into a needle early on in the lesson and long before any other student. She had high expectations for Hermione, and was thus disappointed in her when Hermione claimed she tried to fight the troll that entered the school in 1991 on her own, in order to cover up for Harry and Ron. Whenever Hermione and her friends would get into trouble, McGonagall almost inevitably looked to Hermione to be the most sensible one.[21]

McGonagall was noticeably upset when Hermione was petrified in 1993, even granting Harry and Ron permission to skip a class so they could visit Hermione in the hospital wing.[23] The following school year, she helped arrange for Hermione to be granted a Time-Turner to take extra classes.[15] When the professor was injured with four Stunning Spells in 1996, Hermione was very upset and worried for her.[22] Hermione seemed to regard her head of house as a role model, while Professor McGonagall, in spite of her sternness, was obviously quite fond of Hermione and expected great things of her.

Later, after McGonagall became headmistress of Hogwarts and Hermione became a member of the Ministry of Magic, McGonagall granted her permission to use notes left to the Hogwarts Archives, written by Albus Dumbledore, in her re-translation of The Tales of Beedle the Bard , demonstrating McGonagall's trust in her former pupil.

Viktor Krum

Viktor Krum, her friend and Yule Ball date

Viktor Krum, a renowned professional Quidditch player and student of Durmstrang, came to Hogwarts in 1994 for the Triwizard Tournament, in which he was a Champion. He took to following Hermione into the library, watching her and trying to "pluck up the courage" to speak to her. Eventually, he asked her to be his date to the Yule Ball, and Hermione accepted. Their arrival together caused something of a stir, given Viktor's fame and Hermione's exceptional, and rather unexpected, beauty.

Hermione was Viktor's 'hostage' during the Second Task of the Tournament. After he pulled her from the lake, Viktor told Hermione that he had never felt about someone the way he felt about her, and invited her to visit him in Bulgaria over the summer.[24] At some point, it is alleged by Ginny Weasley during a confrontation with her brother Ron, that he and Hermione shared a kiss during that period.[25] Whether or not Ginny was just trying to get under Ron's skin or if this actually happened is unknown. What is known is that their relationship never became serious enough for her to visit him in Bulgaria, they kept in contact through letters over the years.[22] They met again at the wedding of Bill Weasley and Fleur Delacour in 1997, where Viktor complimented Hermione and was disappointed to learn that she had "sort of" begun a romance with Ron Weasley.[6]

Lavender Brown, her roommate and rival

Hermione's roommates at Hogwarts were fellow Gryffindors Lavender Brown and Parvati Patil as well as Fay Dunbar and another girl. While Lavender and Parvati swiftly became best friends, Hermione was not very close to either of them. Although the girls did not dislike each other, they had very different interests and sometimes clashed as a result.

For example, Hermione scorned Divination, Lavender and Parvati's favourite subject, and accidentally upset Lavender with her clumsy attempt to comfort her over the death of her rabbit.[15] Hermione was also angry with Lavender for doubting Harry Potter's assertion that Lord Voldemort had returned in 1995 and snapped at her about it.

ParvatiPoA
Parvati Patil, her roommate

When Lavender began dating Ron Weasley, she was very upset and confided in Harry about her feelings. Once they broke up however, Hermione chose to not display open affection towards Ron so Lavender's feelings would not get hurt. She also came to Lavender's rescue during the Battle of Hogwarts, blasting Fenrir Greyback away from her.[6]

Hermione had a less tumultuous relationship with Parvati, although the two were not close. During Hermione's first year at Hogwarts, she hugged Parvati after Harry caught the Snitch at a Quidditch game. Parvati was noted to feel guilty after laughing at Ron's cruel teasing of Hermione in Transfiguration, and the two discussed Hermione's attendance of the Slug Club Christmas party with Cormac McLaggen. As Parvati looked “positively agog” at Hermione confiding in her,[25] it can be assumed that Hermione seldom discussed personal matters with her room mates.

Draco Malfoy

Draco Malfoy (HBP promo)
Draco Malfoy, her school bully

Draco Malfoy, of an old and wealthy pure-blood family with Death Eater ties, was raised to believe in the inferiority of Muggle-borns, and thus treated Hermione with disdain. This was probably exacerbated by Hermione's friendship with Harry and Ron, who shared a strong enmity with Draco from virtually the moment they met, and her beating Draco in school marks, for which his father berated him.[23] Draco frequently called Hermione the disparaging term "Mudblood," which usually set off the tempers of her friends — and the entire Gryffindor Quidditch team when he first said it to her face in 1992[23] — but Hermione tended to ignore Draco and urged Harry and Ron to do the same.

Occasionally she would snap back at him, and in their third year, she even slapped him when he mocked Rubeus Hagrid for being upset over the impending execution of Buckbeak, for which Draco was largely responsible.[15]

In spite of his prejudice and dislike toward Hermione, Draco was reluctant to confirm her identity when he was asked to do so by his parents and aunt Bellatrix in 1998, avoiding even looking at her. As an adult sobered by his wartime experiences, Draco was civil towards Hermione and her friends, and friendly with her nephew, Albus Potter.[6]He even found the idea of taking orders from her during their ambush in 1981 of Delphini to be darkly humorous. Draco's civility towards Hermione during this time was likely reinforced due to her being the Minister For Magic in Britain at the time, and possibly due to her relations to Albus Potter, the best friend of his own son, Scorpius.

Rubeus Hagrid, her friend and professor

Rubeus Hagrid was the Gamekeeper and Care of Magical Creatures professor at Hogwarts, as well as a member of the Order of the Phoenix during the First and Second Wizarding Wars. Since Hagrid had met Harry Potter prior to the start of Hermione's first year at Hogwarts, Hermione grew closer to Hagrid as her friendship with Harry developed, eventually coming to visit him in his hut regularly with Harry and Ron Weasley. In their second year, Hagrid comforted Hermione when she was called a "a filthy little mudblood" by Draco Malfoy.

Though she disapproved of Hagrid's penchant for collecting dangerous pets, she tended to more pro-actively support him in his efforts to care for them than Harry and Ron, as when Hagrid was attempting to appeal the execution of Buckbeak and raise his half-brother Grawp. In turn, it was Hagrid who encouraged Ron and Harry to re-think their treatment of Hermione when the three had a brief falling out over Hermione getting Harry's new Firebolt confiscated in their third year. When Dolores Umbridge threatened Hagrid's job during the 1995-1996 school year, Hermione advised him to teach only materials related to their O.W.Ls, so as not to give Umbridge any excuse to fire him, and worked tirelessly to keep him on track.

Hagrid remained close to the trio throughout their time at Hogwarts, and fought various battles in the course of the Second Wizarding War. In 2017, Harry's sons planned to meet Hagrid in his hut for tea soon after arriving at school, and it's very likely that Hermione and Ron's daughter would have been joining them.

Remus Lupin, her professor and friend

Hermione was among the students who were very impressed by Remus Lupin's teaching in 1993, when he was appointed Defence Against the Dark Arts professor. Hermione deduced he was a werewolf during the school year, yet chose to keep it a secret in order to respect his privacy. Towards the end of the year, however, Lupin admitted that he was a werewolf to Harry, Ron and Hermione whilst in the Shrieking Shack. Following the events in this dilapidated building, Lupin became fully prepared to help Sirius Black kill Peter Pettigrew, the wizard who betrayed James and Lily Potter to Voldemort.

However, thanks to Harry's intervention, they chose not to commit the murder, inadvertently allowing Pettigrew to escape. Lupin had referred to Hermione as the cleverest witch of her age he had ever seen before to this. Hermione, meanwhile, did not concern herself with Lupin's lycanthropy, she judged him only by his good nature and the content of his character.

Hermione met Lupin again in 1995 at the Headquarters of the Order of the Phoenix. She and Lupin both fought against the Death Eaters during the Battle of the Department of Mysteries in 1996, and survived (despite Hermione being side-swiped by Dolohov's curse). They also fought in the Battle of the Astronomy Tower and the Battle of the Seven Potters alongside, both emerging alive and relatively unscathed on the two occasions. Hermione was pleased to learn that Lupin had married Nymphadora Tonks before the Battle of the Seven Potters began, and became even more joyful at the news of Lupin's son, Ted Lupin, being born; joining in on the celebratory festivities at Shell Cottage. Hermione was devastated by Lupin's and Tonks' deaths in 1998, becoming friendly with their orphaned son, Teddy Lupin, later on in life.

Sirius Black, her friend

Hermione first learned about Sirius Black in 1993, when he escaped Azkaban. The wizarding world at large knew of him as the wizard who murdered twelve Muggles and a wizard (Peter Pettigrew) with a single curse. Very few knew of his affiliation with the Potters and those who did also believed that Sirius had betrayed James and Lily Potter to Voldemort by revealing their location at Godric's Hollow. During the events at Hogwarts in 1993, Hermione along with Harry, Ron and Lupin discovered that, contrary to their previous beliefs, Sirius Black had never committed the murders for which he had been incarcerated, nor had he betrayed his closest friends.

The trio managed to save Sirius and Lupin from being subjected to the Dementor's Kiss at the hands of Severus Snape by firing three simultaneous Disarming Charms at him. Snape was blasted off his feet and knocked unconscious, allowing Harry, Ron and Hermione to continue their interrogation of Sirius who later revealed that Pettigrew had disguised himself in his rat Animagus form for twelve years in order to escape justice and the wrath of Voldemort's remaining Death Eaters. However, upon exiting the Whomping Willow's secret passageway together, Pettigrew shrewdly used Lupin's werewolf transformation as a distraction and escaped. Sirius was soon apprehended and locked in Filius Flitwick's office to await the Dementor's Kiss. Harry and Hermione would later use the latter's Time-Turner to rescue Sirius, who became deeply grateful to both of them.

In 1994, Hermione, Harry, and Ron visited Sirius at the cave off Hogsmeade village he was hiding in, bringing him food. Here they discussed the many mysteries that had occurred during that year, the trio learning valuable pieces of information regarding the imprisonment of Barty Crouch Jr After the events of the Third Task, Sirius (while in his Animagus form) joined Hermione, Ron and Molly Weasley at Harry's bedside, each indicating their affections for the latter.

Hermione and Sirius would not meet again until the summer of 1995, at the Headquarters of the second Order of the Phoenix. Sirius was obliged to remain in 12 Grimmauld Place for his own safety (his innocence not yet recognised by the Ministry). Sirius was rather disappointed when Harry was allowed to return to Hogwarts, Hermione pointing out that he had probably been secretly wishing that Harry had been expelled from school so that they could both stay at Grimmauld Place and be "outcasts together". Hermione expressed an even deeper understanding of Sirius's emotions when she stated her opinion to Harry that Sirius was attempting to relive his happier school days through his godson. Harry ignored this and became slightly agitated at the suggestion that Sirius might be guilty of such a crude, selfish mentality. However, she severely disapproved of his indifferent and occasionally cruel treatment of his house-elf, Kreacher, despite the fact that Kreacher initially appeared to be disgusted by her and addressed her as "the Mudblood" (which Hermione often attributed to Kreacher being senile due to his old age.)

She also thought that Sirius was attempting to live vicariously through her, Harry and Ron when he encouraged them to form Dumbledore's Army, but the two boys became angry and snapped at her when she expressed this belief. Sirius was eventually killed by Bellatrix Lestrange in the Battle of the Department of Mysteries, much to the dismay of his friends and loved ones. Hermione was devastated by his death, and often tried to provide comfort to Harry, who had been even more deeply affected by the tragedy. At the end of the Second Wizarding War, Hermione became godmother to Harry's eldest son, James Sirius, whose first and middle name was derived from James Potter and Sirius Black respectively.

Severus Snape

Severus Snape
Severus Snape, her professor

Severus Snape was the Potions Master during most of Hermione's time at Hogwarts. He was also the Head of Slytherin House, and tended to openly show preferential treatment for the students of his own house, while being quick to criticise and deduct points from Gryffindor students. He was particularly unpleasant towards the trio, and regularly punished and verbally assaulted Harry and Ron for their poor to mediocre performances in his class. He could not do the same to Hermione, as she was the best student in the year and instead mocked her for things like being an "insufferable know-it-all," once even snidely insulting the size of Hermione's teeth.[24]

Despite his pre-existing dislike for Gryffindor,[6] Snape's treatment of Hermione likely had more to do with her close friendship with Harry. Despite this, Hermione was still seen to defend Snape on occasion when Harry and Ron blamed him for evil deeds which occurred in Hogwarts, like setting the troll in the dungeon and trying to steal the Philosopher's Stone in Harry's first year. After Dumbledore's death, she like many, believed that Snape was a coward who killed a man who trusted him more than anyone. It is unknown exactly how she reacted to learning of Snape's true motives and allegiance, but given her personality, it is highly likely that she came to both forgive her former Professor's cruelty, and even admire him for his bravery.

Albus Dumbledore, her former headmaster

As with most aspects of the wizarding world, Hermione read about Albus Dumbledore shortly after learning that she was a witch. She first met the Hogwarts headmaster during her her first year at the school, in 1991, and quickly came to respect Dumbledore's immense power and seemingly infinite wisdom. Although Dumbledore was not as close with her as he was with Harry Potter, he showed great insight into her character very early on. She was one of only three students Dumbledore bequeathed a personal item, as he believed her to be, along with Ron Weasley, trustworthy of accompanying Harry on his mission to destroy Voldemort's Horcruxes.

He respected her intellect, perspicacity, and level-headedness, admitting to Harry that he had counted on Hermione to keep things in perspective when the trio finally discovered the existence of the Deathly Hallows. Hermione was devastated when Dumbledore was killed, and visited his portrait with Harry and Ron after the Battle of Hogwarts to determine the fate of the Hallows.

Crookshanks
Ron Weasley : "Hermione, that thing nearly scalped me!"
Hermione: "He didn't mean to, did you, Crookshanks?... Poor Crookshanks, that witch said he'd been in there for ages; no one wanted him."
Ron Weasley : "I wonder why."

Crookshanks

Crookshanks was Hermione's large, bandy-legged, half-Kneazle, ginger-coloured pet cat since she bought him from the Magical Menagerie in Diagon Alley, in 1993. She seemed to think he was gorgeous, although no one else had wanted to buy him when he was still being sold at the Menagerie, and believed he was very clever; the latter proved to be quite true during the 1993-1994 school year, when Crookshanks recognised that Hermione had left him at the Burrow before Bill and Fleur's wedding, most likely had been left in care of Mrs Weasley or Ginny but it is possible that they were reunited after the war.

Cormac McLaggen
Harry Potter: "What's happened to you?"
Hermione: "Oh, I've just escaped — I mean, I've just left Cormac. Under the mistletoe... Cormac hasn't asked me one single question about myself, no, I've just been treated to 'A Hundred Great Saves Made by Cormac McLaggen' non-stop ever since — oh no, here he comes!"
— Hermione avoiding her date[src]
Mclaggen
Cormac McLaggen

Cormac McLaggen was a Gryffindor student one year above Hermione. The two became acquainted in 1996 through the Slug Club, of which they were both members, though Hermione did not think highly of McLaggen. When she overheard him insulting Ron and Ginny during Quidditch try-outs, Hermione struck him with the Confundus Charm, undermining his abilities as a Keeper.

Later in the year, when Hermione was furious with Ron for dating Lavender Brown, she decided to attend Professor Slughorn's Christmas party with McLaggen because she knew Ron despised him. McLaggen was apparently interested in Hermione, as he escorted her to the party and was very forward with her romantically while there. This, as well as his tendency to boast about himself, put Hermione off, and she soon abandoned him for the company of Harry and Luna before leaving the party altogether to avoid him.[25] It can be assumed that the party was the end of their interaction.

Pansy Parkinson

Pansy Parkinson

Pansy was more or less Hermione's polar opposite: where Hermione was compassionate (i.e. SPEW), independent, and incredibly helpful to nearly anyone who needed it, Pansy was petty, mocked just about every non-Slytherin student she encountered (as well as Hagrid), and was little more than one of Draco Malfoy's more sycophantic lackeys. Pansy had a tendency to taunt and snipe at Hermione, Harry, and Ron at any given opportunity, though Hermione rarely seemed more than slightly irritated by her comments; the major exception to that most likely would have been Pansy's attempt to surrender Harry to Lord Voldemort shortly prior to the start of the Battle of Hogwarts.

Rita Skeeter

— Hermione vows retribution against Rita Skeeter[src]

Rita Skeeter

While covering the Triwizard Tournament in Hermione's fourth year, Daily Prophet journalist Rita Skeeter wrote a number of exaggerated and slanderous stories about Harry Potter and his friends, including one that outed Rubeus Hagrid as a half-giant. Harry and Hermione angrily confronted Rita about this. After Hermione insulted her, Rita published another article that portrayed Hermione as manipulative and ambitious, claiming that she was toying with the emotions of both Harry Potter and Viktor Krum. This resulted in Hermione receiving several letters of hate mail, including a few Howlers and at least one envelope filled with bubotuber pus.

Hermione became obsessed with getting back at Rita and uncovering how she was getting all of her information. Finally, near the end of the school year Hermione realised that Rita Skeeter was an unregistered Animagus. She caught Rita in her beetle form attempting to eavesdrop on Harry in the Hospital Wing after the Third Task. Hermione sealed her inside a small bottle. Hermione blackmailed Rita into giving up writing for one year, otherwise her unregistered status would be revealed. As the penalties are apparently quite severe, Rita had no choice but to comply.

When the Ministry of Magic began using the Daily Prophet in its smear campaign against Harry, Hermione was again able to blackmail Rita, this time into writing an article for The Quibbler that would allow Harry to tell his side of the story. After her one year punishment was over, Rita went back to writing with as much enthusiasm and as little scruples as she had before, although it's unknown if she ever crossed Hermione again. Given her notable lack of commentary regarding Hermione during the 2014 Quidditch World Cup in Egypt, it is likely that Rita remained extremely wary of Hermione's wrath 19 years following her being blackmailed by the prodigious witch.

Dolores Umbridge
"That foul, evil old gargoyle! We're not learn how to defend ourselves, we're not learning how to pass our O.W.L.s... she's taking over the entire school!"

Dolores Umbridge
Dolores Umbridge, her former professor and enemy

Dolores Umbridge was appointed Defence Against the Dark Arts professor by the Ministry of Magic, in 1995. She was a sadistic woman who enjoyed punishing and torturing students using the Black Quill, most notably when she forced Harry Potter to carve "I must not tell lies" into the back of his own hand. Umbridge was as obsessed with blood-status as the Death Eaters, and had a particular hatred of what she called "half-breeds." Hermione, like most of the students and staff at Hogwarts, hated Umbridge. Hermione was one of the first to pick up on the true motives behind Umbridge's appointment at the magical school. In turn, Umbridge was not too fond of Hermione, who was not only Muggle-born, but was also probably far too perceptive for her liking, as well as being outspokenly opposed to a purely theoretical defensive magical education.

When Umbridge planned to use Veritaserum and then the Cruciatus Curse on Harry, Hermione was the one who came up with the lie that led to them venturing into the Forbidden Forest and Umbridge eventually being dragged away by a herd of offended centaurs.

Hermione next met Umbridge a second time at the Ministry of Magic in 1997, when Hermione was disguised as Mafalda Hopkirk through the usage of Polyjuice Potion. Umbridge was, at the time, interrogating "Mudblood" witches and wizards, prior to sending them to Azkaban. Harry stunned Umbridge and retrieved Salazar Slytherin's Locket, one of Voldemort's hocruxes which Umbridge had taken from Mundungus Fletcher and was attempting to pass off as a family heirloom and proof of her relation to the Selwyn family. Hermione replaced the locket by duplicating it with the Geminio spell so Umbridge would not know that it had been taken from her. The trio proceeded to free all the Muggle-Borns awaiting interrogation.

Suffice it to say that Umbridge personified everything that Hermione detested and loathed in Wizarding society, including but not limited to racial prejudice, sadism, malicious misuse of power, authoritarianism, and pure-blood supremacy.

Lord Voldemort, her enemy

Hermione first learned about Lord Voldemort, the most dangerous Dark Wizard of all time, after reading about him sometime before she began attending Hogwarts School of Witchcraft and Wizardry . During her first year, she and Ron Weasley helped Harry Potter reach the Philosopher's Stone and protect it from Voldemort.

A year later, Hermione, after fully recovering from her Polyjuice mishap, was shown T. M. Riddle's Diary by Harry. At first enthusiastic that the book might have "magical powers", Hermione first came up with the theory that it was Tom Riddle who originally "caught" the "Heir of Slytherin" when the Chamber of Secrets had been opened fifty years prior. She also correctly guessed that the Diary contained the answers to the Chamber's location, how to open it, and the true identity of Slytherin's monster. Thinking that the Diary was written in invisible ink, the attempted to use the spell Aparecium, and then a Revealer, on the object, but to no effect. Later on, when Harry went to the trophy room to try to learn more about Tom Riddle, he was accompanied by an "interested" Hermione. When Ron compared Riddle to Percy "in disgust", mentioning the former as being "Prefect, Head Boy... probably at the top of every class", Hermione responded in a "slightly hurt" voice, "You say that like it's a bad thing."

Later on, she also correctly deduced that Riddle had "caught the wrong person", and that "it was some other monster [not Hagrid's Acromantula, Aragog] that was killing people". Later on, after Harry mentioned "hearing the voice" again before the Quidditch match between Gryffindor and Hufflepuff, Hermione ran immediately to the Library to research, where realised that Slytherin's monster was a basilisk. Tearing the page out of the book, and putting it in her right hand, she left the Library, where she warned the first person she met, Penelope Clearwater, to look around corners with her mirror. However, both Hermione and Penelope were petrified by Salazar Slytherin's Basilisk, which was controlled by Tom Riddle's memory.

In 1995, she learned that the Dark Lord had returned and supported Harry against the Ministry's denial and smear campaign. She also fought in the Battle of the Department of Mysteries to prevent Voldemort from obtaining a vital prophecy, but was severely injured and rendered unconscious. In 1997, she left Hogwarts to help Harry and Ron find and destroy Voldemort's horcruxes. She personally destroyed Helga Hufflepuff's Cup using a basilisk's fang. She later witnessed Harry's defeat of Voldemort in the Battle of Hogwarts.

However, Hermione made very little direct contact with Voldemort, truly seeing him for the first time during the Battle of the Department of Mysteries. Possibly the closest connection Hermione and Voldemort shared was through the former wearing Salazar Slytherin's Locket whilst travelling with Harry Potter and Ron Weasley in 1997. The Horcrux locket was worn by all three for regular, though limited, periods of time, inadvertently allowing the portion of soul within to access the wearer's thoughts, emotions and deepest fears. The Horcrux had learned enough about Hermione to use hers and Harry's likenesses in emotionally torturing Ron, reflecting Ron's deepest fears of Hermione preferring Harry to him. Because the Horcrux had become so disconnected from the once whole soul of Tom Riddle, the physically bodied Voldemort was not aware of any of these events, nor of the information the Horcrux had gained dangling around the necks of Harry and his closest friends.

Although they had very little direct contact, Hermione and Voldemort are sometimes similar: both are "model students" who achieved outstanding grades in NEWTS. Both were Prefects, although Voldemort was Head Boy while Hermione skipped school during what would have been her seventh year due to political persecution, preventing her from being Head Girl that year (it is possible that Hermione became Head Girl when she went back to finish her seventh year after Voldemort's final destruction). They both came from Muggle backgrounds, but Voldemort was raised in an orphanage while Hermione was brought up in a loving Muggle family.

Bellatrix Lestrange
"You're lying, filthy mud-blood, and I know it! You have been inside my vault in Gringotts! Tell the truth, tell the truth! What else did you take? What else have you got? Tell me the truth or, I swear, I shall run you through with this knife! What else did you take, what else? ANSWER ME! CRUCIO!"
—Bellatrix interrogating Hermione[src]

Bellatrix Lestrange, an enemy

Bellatrix Lestrange was one of Voldemort's most fanatically loyal followers; Hermione initially knew her as one of the Death Eaters involved in torturing and permanently incapacitating Frank and Alice Longbottom, though she also witnessed Bellatrix murder Sirius Black at the Battle of the Department of Mysteries, in 1996.

During the Skirmish at Malfoy Manor, Bellatrix chose to torture Hermione, who, as a Muggle-born, Bellatrix felt was most dispensable (though, as a "blood traitor," Ron Weasley was a close second), in order to discover where and how the trio had managed to acquire Godric Gryffindor's Sword. During the interrogation, Bellatrix used her knife to carve the word "mudblood" on Hermione's arm.[37] Hermione later used one of Bellatrix's hairs obtained in the skirmish to make Polyjuice Potion and break into the Lestrange Vault at Gringotts Wizarding Bank. Hermione, Ginny, and Luna duelled against Bellatrix during the final battle, but were made to stand aside by Molly Weasley, who eventually killed Bellatrix herself.

Dumbledore's Army
"I also think we should have a name... It would promote a feeling of team spirit and unity, don't you think?"
—Hermione on naming the Army[src]
Dumbledore's Army
Dumbledore's Army, her allies

Dumbledore's Army was essentially Hermione's brainchild, though she co-founded it with Ron and Harry during the 1995–1996 school year. After Dolores Umbridge informed her Defence Against the Dark Arts students that they would not be using any magic, claiming a theoretical education would suffice, a furious Hermione (fearful of being ill-equipped to deal with the reborn Lord Voldemort and the upcoming O.W.L.s) conceived of the organisation as a means of allowing any student interested in actually practising defensive magic to do so. Though the secret classes were taught by Harry, Hermione arranged the initial meeting at the Hog's Head, created the DA's method of covert communication, and jinxed their member list to reveal any betrayal.

All of the DA members grew closer over the course of the year (with the exceptions of Marietta Edgecombe, who betrayed the DA to Umbridge, and later Zacharias Smith, who deserted them), as evidenced by their reunion in 1997, and their enthusiasm in supporting Harry and mobilising against the invading Death Eaters during the Battle of Hogwarts. Moreover, the DA truly cemented Hermione's friendships with Luna Lovegood and Neville Longbottom, who were the only members, aside from Ginny Weasley, to fight alongside Hermione, Harry, and Ron at the Battle of the Department of Mysteries and the Battle of the Astronomy Tower.

Hermione's relationship with Cho Chang was two-sided; while Hermione gave Harry advice on how to build a successful relationship with Cho, Cho grew increasingly jealous of Harry's close friendship with Hermione, believing that the two of them were romantically involved. Because of this, Cho went into a dramatic and tear-filled departure from her date with Harry when he mentioned that he promised to meet with Hermione, who would later comment sadly on how Harry went the wrong way on telling Cho about the appointed meeting. When Cho attempted to insult Hermione for jinxing her friend Marietta Edgecombe for betraying DA, Harry defended her and in turn insulted Marietta. However, when Hermione returned to Hogwarts during the last stand against Voldemort, any negative feelings for each other seemed to have evaporated, as Cho welcomed the trio.

Order of the Phoenix

Hermione: "Of the Order of the Phoenix. It's a secret society. Dumbledore formed it back when they first fought You-Know-Who."

OotP
The original Order of the Phoenix, her allies

Hermione first heard about the Order of the Phoenix in 1995, when she, Harry and Ron spent several weeks at the Order's headquarters. Through her time at Grimmauld Place, Hermione got to know Alastor Moody, the most famous Auror of modern times, known for rounding up several Death Eaters after the First Wizarding War and for his growing paranoia. He and Hermione fought together in the Battle of the Department of Mysteries, and later, in the Battle of the Seven Potters, where Moody was killed by Voldemort's own hand. Hermione, like the rest of the Order, was shocked and horrified by the death of such a skilled Auror, "the consummate survivor,"[6] and disgusted by Mundungus Fletcher's desertion. Hermione, who had known Fletcher as a petty criminal who had stolen a number the Black family heirlooms shortly after Sirius Black's death, aside from being a member of the Order, took part in interrogating Fletcher, when she, Harry and Ron realised Salazar Slytherin's Locket had been among the items stolen from Grimmauld Place.

Hermione had great respect for Kingsley Shacklebolt, a skilled Auror and eventual Minister for Magic, who was known as "Royal" on Potterwatch, and who saved countless lives (including Hermione, Ron and Harry's) when he sent his Patronus to warn the attendees of Bill and Fleur's wedding that the Ministry had fallen, and with it, the protections surrounding the Burrow. Another member of the Order responsible for saving the trio was Aberforth Dumbledore, Albus' younger brother. Though Hermione, Harry and Ron had known him for some time as the owner of the Hog's Head Pub, they finally met him in 1998, just before the Battle of Hogwarts, when he just barely managed to get them out a trap set by Death Eaters. Prior to that, he sent Dobby to rescue them, along with Dean Thomas, Luna Lovegood, Garrick Ollivander and Griphook the Goblin, from the Malfoy Manor; as it turned out, Aberforth had acquired Sirius Black's two-way mirror from Mundungus Fletcher, and been keeping an eye out for Harry.

Nymphadora Tonks, a funny, Metamorphmagus witch, who had become a good friend of Hermione's, died along with her husband and fellow member of the Order, Remus Lupin, during the Battle of Hogwarts. As their son, Ted Lupin, was Harry's godson and was also dating Hermione's niece, Victoire by 2017, it's likely Hermione remained quite close to him.

Septima Vector
Hermione also had a good relationship with her Arithmancy Professor Septima Vector. Many students disliked Vector because of her strictness. However, Hermione said Arithmancy was her favourite subject at Hogwarts. She also never complained about Vector's strictness. During her third year, Hermione joined her class and used a time-turner to get to one of the lessons[38]. Then in her fourth year, Hermione and the other students got no homework from Septima Vector on the first day of term[39] and she adamantly refused to skive Arithmancy[40].
