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

J.K. Rowling has identified herself with Gryffindor, one of Hogwarts’ four houses.

In the Harry Potter books, the Sorting Hat places students into Gryffindor, Hufflepuff, Ravenclaw or Slytherin. Gryffindor is associated especially with courage, nerve and chivalry, and it is the house of Harry Potter, Ron Weasley and Hermione Granger.

Rowling’s connection with Gryffindor is a biographical statement about the author, not a plot event in the novels. She has discussed the house in interviews and fan-related contexts, which is why the answer is often reported as her Hogwarts affiliation.

The question can be confused with Rowling’s favourite character or with the house she might have chosen for a fictional student. Those are different ideas. The canonical house names are distinct, and Rowling’s stated association is Gryffindor.
