What is the title of the third Harry Potter novel by J.K. Rowling?

The third Harry Potter novel by J.K. Rowling is Harry Potter and the Prisoner of Azkaban.

Bloomsbury published the novel in the United Kingdom on 8 July 1999. It follows Harry’s third year at Hogwarts and introduces Sirius Black, a prisoner who has escaped from Azkaban wizarding prison. The plot also develops the backstory of Harry’s parents and their school friends.

The book comes after Harry Potter and the Philosopher’s Stone and Harry Potter and the Chamber of Secrets. It is followed by Harry Potter and the Goblet of Fire, which expands the story beyond Hogwarts through the Triwizard Tournament and the return of Lord Voldemort.

The film adaptation of Prisoner of Azkaban was released in 2004 and directed by Alfonso Cuarón. Because the titles share a repeated “Harry Potter and the...” structure, readers sometimes mix up the middle books, but the prisoner in this title is Sirius Black.
