Ravenclaw is one of the four Houses of Hogwarts School of Witchcraft and Wizardry, founded by Rowena Ravenclaw. Members of this house are characterised by their wit, learning, and wisdom. Its house colours are blue and bronze, and its symbol is the eagle.[3] The house ghost, who in life was the daughter of the house's founder Rowena Ravenclaw, is the Grey Lady[4]. Many great wizards and witches have come from this house, including Filius FlitwickGarrick Ollivander and Luna Lovegood.

Ravenclaw roughly corresponds with the element of air[5]; the House colours blue and bronze were chosen to represent the sky and eagle feathers respectively, both having much to do with air[6]. Ravenclaw House prizes learning, wisdom, wit, and intellect in its members.[3] Thus, many Ravenclaws tend to be academically motivated and talented students. Hermione Granger, an extremely intelligent witch and the top student in her year, was sorted intoGryffindor, though she admitted that the Sorting Hat had seriously considered placing her in Ravenclaw.[7]

Students in Ravenclaw can also be quirky and possess unusual intellectual interests. Ravenclaws generally accept and celebrate these eccentrics. Ravenclaw House appears to have little rivalry with the other houses, except in Quidditch (in which case it is most fiercely competitive with Hufflepuff). Harry Potter believed that they tended to side with Gryffindor in its rivalry with Slytherin, as did Hufflepuff house. However, during the 1994 Triwizard Tournament, Ravenclaws supportedHufflepuff Champion Cedric Diggory over Harry.[8] Notably, many Ravenclaws joined Dumbledore's Army and fought in the Battle of Hogwarts along with Gryffindors and Hufflepuffs.
