Apparition is a magical method of transportation. It is basically the magical action of travelling by having the user focus on a desired location in their mind. After the user is properly focused they then disappear from their current location and instantly reappear at the desired location. In short, Apparition is a form of teleportation. It is by far the fastest way to get to one's desired destination, but is tricky to pull off correctly and disastrous if botched up.

Apparition is a popular method of travel in the wizarding world, though it is stated that plenty of adult witches and wizards don't bother with it. These witches and wizards prefer brooms, Floo Powder or portkeys. Albus Dumbledore once noted that most people vomit the first time they successfully Apparate. According to Harry Potter Apparition feels like being "forced through a very tight rubber tube.
