Which Hogwarts house is J.K. Rowling’s official house on Pottermore?

J.K. Rowling’s official Pottermore house is Gryffindor.

Gryffindor is one of the four houses at Hogwarts School of Witchcraft and Wizardry. It was founded by Godric Gryffindor and is associated with courage, bravery, nerve, and chivalry. The house’s emblem is a lion, and its traditional colors are scarlet and gold.

In the Harry Potter novels, students are placed into houses by the Sorting Hat. Harry Potter, Ron Weasley, Hermione Granger, and many other central characters belong to Gryffindor. The house competes with Slytherin and the other houses for the annual House Cup.

Rowling’s own online sorting result has sometimes prompted discussion because readers may associate her with Ravenclaw’s emphasis on learning or Hufflepuff’s loyalty. However, the official Pottermore sorting result identified her as Gryffindor, making that the canonical answer to this question about her public profile.
