Harry Potter and the Cursed Child is the stage play based on a story by J.K. Rowling that follows an adult Harry Potter. The play premiered in London’s West End in 2016.

The story is set nineteen years after the events of Harry Potter and the Deathly Hallows. Harry is an employee of the Ministry of Magic and has three children. The plot particularly follows his younger son, Albus Severus Potter, and Albus’s friendship with Scorpius Malfoy, the son of Draco Malfoy.

Rowling developed the story with playwright Jack Thorne and director John Tiffany. Thorne wrote the published stage script, so the play is not a conventional eighth novel written solely by Rowling. Its official title is Harry Potter and the Cursed Child, Parts One and Two, and it was presented as a two-part theatrical production.
