Non-magic people, commonly known as Muggles in Great Britain, No-Maj(e)s in the United States,among other names (see below), were humans who were born to two non-magical parents and were incapable of performing magic. Non-magic people were not to be confused with Squibs, who also lacked magic but were born to at least one magical parent.

Most non-magic people had been unaware that magic and the wizarding world existed since the establishment of the International Statute of Wizarding Secrecy in 1692, as wizards had organised their own society largely separate from the non-magic world. Exceptions included close relatives of wizards and witches and heads of government (such as the British Prime Minister)
