Which Harry Potter book was the last of J.K. Rowling’s original seven novels?

Harry Potter and the Deathly Hallows was the last of J.K. Rowling’s original seven Harry Potter novels.

The book was published in the United Kingdom on 21 July 2007. It follows Harry, Ron Weasley, and Hermione Granger after they leave Hogwarts to search for objects connected to Voldemort’s power. The story brings the main conflict to its conclusion and includes the Battle of Hogwarts.

Deathly Hallows is the seventh main novel, following Harry Potter and the Half-Blood Prince. Rowling had planned the series as seven books, matching the usual number of years of study at Hogwarts, although the final book takes place largely away from school.

Later publications expanded the Wizarding World, including Harry Potter and the Cursed Child and companion works. Those releases do not change Deathly Hallows’ status as the concluding volume of Rowling’s original seven-novel sequence.
