A hag is an ugly, old woman, often associated with witchcraft and supernatural powers. In folklore and childrens tales, hags are often portrayed as fairy or goddess-like beings with magical abilities. The term "hag" is sometimes used interchangeably with "crone". In English and Anglophone North American folklore, a "Night Hag" or "the Old Hag" is a nightmare spirit that sits on a sleepers chest and sends nightmares to them. The term "hag" is also used in the Harry Potter universe to describe a savage being that looks like an ugly, old witch. However, it is important to note that using the word "hag" to translate terms found in non-English (or non-modern English) is contentious, since the use of the word is sometimes associated with misogyny.
