Which J.K. Rowling novel features the Triwizard Tournament?

Harry Potter and the Goblet of Fire features the Triwizard Tournament.

Published in 2000, the fourth Harry Potter novel brings together champions from three European wizarding schools: Hogwarts, Beauxbatons, and Durmstrang. The competitors are selected by the Goblet of Fire and must complete three dangerous tasks involving dragons, an underwater rescue, and a maze.

Harry is unexpectedly chosen as a fourth champion, despite being under the minimum age requirement. He competes alongside Cedric Diggory, Fleur Delacour, and Viktor Krum. The tournament’s final task leads Harry and Cedric to a portkey and the graveyard where Voldemort returns to a physical body.

The book is often remembered as the point where the series moves decisively from school adventure toward open conflict. The film adaptation, released in 2005, also centers on the tournament but condenses several events and characters from the novel.
