Jason Momoa Aquaman and the Lost Kingdom is an upcoming American superhero film based on DC Comics featuring the character Aquaman. Produced by DC Films, The Safran Company, and Atomic Monster Productions, and set for distribution by Warner Bros. Pictures, it is intended to be the sequel to Aquaman (2018) and the thirteenth film in the DC Extended Universe (DCEU). The film will be directed by James Wan from a screenplay written by David Leslie Johnson-McGoldrick, and stars Jason Momoa as Arthur Curry / Aquaman alongside Amber Heard, Patrick Wilson, Dolph Lundgren, and Yahya Abdul-Mateen II.

Momoa pitched a story for an Aquaman sequel during production of the first film, but Wan did not want to rush the next film. He agreed to oversee development of the sequel in January 2019, with Johnson-McGoldrick signed to write the screenplay a month later. Wan was confirmed to be directing the film in August 2020, and said it would expand on the worldbuilding of the first Aquaman. He announced the title for the sequel in June 2021, with filming beginning later that month in London. Aquaman and the Lost Kingdom is scheduled to be released on December 16, 2022.
