Dynasty Warriors is a 2021 Hong Kong fantasy-action film based on the Japanese video game franchise of the same title by Omega Force and Koei Tecmo.

Directed by Roy Chow, the film stars an ensemble cast from Hong Kong, China and Taiwan, including Louis Koo, Carina Lau, Wang Kai, Tony Yang, Han Geng, Justin Cheung, Gulnazar and Ray Lui.

On 15 March 2016, Suzuki Akihiro, the producer of Koei Tecmo's Dynasty Warriors video game series, and the Hong Kong-based company HMV Digital China announced at the 20th Hong Kong International Film and TV Market that they will be making a live-action film adaptation of Dynasty Warriors.

He also revealed that he had approached Koei Tecmo four years ago and secured the rights to adapt the Dynasty Warriors franchise into a movie.
