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

The fourth Harry Potter novel by J.K. Rowling is Harry Potter and the Goblet of Fire.

Bloomsbury published Harry Potter and the Goblet of Fire in the United Kingdom on 8 July 2000. The novel is the fourth entry in the seven-book sequence and marks a major expansion in scale, introducing the Triwizard Tournament and bringing students from other wizarding schools to Hogwarts.

Harry is unexpectedly entered into the tournament, competing against older champions from Hogwarts, Beauxbatons, and Durmstrang. The story’s final stages also mark a major turning point in the return of Lord Voldemort and the wider conflict.

The title is sometimes confused with the third book, Harry Potter and the Prisoner of Azkaban, or the fifth book, Harry Potter and the Order of the Phoenix. The Goblet of Fire was adapted as the fourth film, released in 2005 and directed by Mike Newell.
