Which 2007 Harry Potter novel was the final book written by J.K. Rowling?

Harry Potter and the Deathly Hallows was the final Harry Potter novel written by J.K. Rowling.

The seventh book was published in the United Kingdom on 21 July 2007. It follows Harry, Ron, and Hermione as they leave Hogwarts to find and destroy the remaining Horcruxes, objects that contain pieces of Lord Voldemort’s soul.

The title refers to three legendary magical objects: the Elder Wand, the Resurrection Stone, and the Cloak of Invisibility. Together they form the Deathly Hallows, although the characters must also confront the moral and historical consequences surrounding their ownership.

The novel concludes the main conflict between Harry and Voldemort and resolves major mysteries introduced earlier in the series. Its adaptation was divided into two films, released in 2010 and 2011. The book’s publication completed the original seven-novel sequence, though Rowling later expanded the setting through companion works, screenplays, and other Wizarding World projects.
