Which Hogwarts house does J.K. Rowling say she belongs to?

J.K. Rowling says she belongs to Gryffindor.

Gryffindor is one of the four houses at Hogwarts School of Witchcraft and Wizardry in the Harry Potter series. The house was founded by Godric Gryffindor and is associated with courage, bravery, nerve, and chivalry. Its house colors are scarlet and gold, and its emblematic animal is the lion.

Rowling has identified herself with Gryffindor in public comments and on the official Pottermore website. This is a personal association with the fictional house rather than a formal result from a real-world test. In the books, students are sorted by the Sorting Hat, which considers their qualities and, in some cases, their preferences.

Harry Potter, Ron Weasley, and Hermione Granger are also Gryffindors, although the series presents important characters from every house.
