Joker: Folie à Deux is an upcoming American musical romance psychological thriller film directed by Todd Phillips from a screenplay co-written with Scott Silver. The sequel to Joker (2019), loosely based on DC Comics characters, Joaquin Phoenix reprises his role as the Joker, with Lady Gaga joining the cast as his love interest, Harley Quinn. Zazie Beetz also reprises her role from the previous film, while Brendan Gleeson and Catherine Keener also join the cast. It is produced by Warner Bros. Pictures and DC Studios in association with Joint Effort.

Joker was conceived as a standalone film, although Warner Bros. intended for it to launch a DC Black film series. Phillips expressed interest in making a sequel, but reiterated that Joker was not set up to have one. The sequel entered development in June 2022, with Gaga and Beetz joining later that year. Principal photography took place in Los Angeles, New York City, and Belleville, New Jersey, from December 2022 to April 2023.

Joker: Folie à Deux is scheduled for a theatrical release overseas on October 2, 2024, followed by the United States two days later on October 4, 2024, by Warner Bros. Pictures.
