Which Hogwarts founder created Ravenclaw house in J.K. Rowling’s Harry Potter series?

Rowena Ravenclaw created Ravenclaw house in J.K. Rowling’s Harry Potter series.

Rowena Ravenclaw was one of the four founders of Hogwarts School of Witchcraft and Wizardry. The house named after her values intelligence, learning, wit, and wisdom. Its emblem is an eagle, despite the house name being associated with a raven in ordinary language.

Ravenclaw’s most famous student in the main novels is Luna Lovegood, whose originality and independent thinking reflect the house’s broader identity. The house’s common room is located in a tower and requires students to answer a riddle to enter.

Rowena’s daughter, Helena Ravenclaw, became the ghost known as the Grey Lady. Helena stole her mother’s diadem, an object later transformed into one of Lord Voldemort’s Horcruxes. That plot detail connects the founder’s history directly to the series’ final conflict.
