Gladiator II (stylized onscreen as GLADIIATOR) is a 2024 epic historical action film directed and produced by Ridley Scott that serves as a sequel to Gladiator (2000). Written by David Scarpa based on a story he wrote with Peter Craig, the film was produced by Scott Free Productions and distributed by Paramount Pictures. It stars Paul Mescal, Pedro Pascal, Joseph Quinn, Fred Hechinger, Lior Raz, Derek Jacobi, Connie Nielsen, and Denzel Washington. Jacobi and Nielsen reprise their roles from the first film, with Mescal replacing Spencer Treat Clark. Mescal portrays Lucius, whose home is invaded by the Roman army led by General Acacius. He seeks revenge against Acacius and fights as a gladiator for Macrinus, a former slave who plans to overthrow the twin emperors Geta and Caracalla.

A sequel to Gladiator was discussed as early as June 2001, with David Franzoni and John Logan set to return as screenwriters. Over the next few years, Scott offered occasional updates, including the possible involvement of the original film's lead actor, Russell Crowe, along with plot ideas about the Roman afterlife and different historical time periods. Development was halted when DreamWorks sold the rights to the property to Paramount in 2006. The film was finally announced in 2018, and Mescal was cast in the lead role in January 2023, with a script by Scarpa. The rest of the cast signed on over the next several months. Filming took place between June 2023 and January 2024, with a five-month hiatus due to the 2023 Hollywood labor disputes.

Gladiator II premiered in Sydney, Australia, on October 30, 2024. It was released in the United Kingdom on November 15 and in the United States on November 22. It received generally positive reviews from critics and has grossed $314 million worldwide.
