Fist of the North Star (Japanese: 北斗の拳, Hepburn: Hokuto no Ken) is a 1986 Japanese adult animated post-apocalyptic martial arts film based on the manga of the same name. It was produced by Toei Animation, the same studio who worked on the TV series that was airing at the time, with most of the same cast and crew working on both projects.

Unlike the TV series, the film is not a direct adaptation of the manga, but instead tells an alternate story that rearranges characters and plot elements from the manga's first 72 chapters. However, the film retains the more violent content of the original manga, which the television series lacked.
