Rurouni Kenshin: The Final (Japanese: るろうに剣心 最終章 The Final, Hepburn: Rurouni Kenshin: Saishūshō – Za Fainaru) is a 2021 Japanese jidaigeki action film film based on the Rurouni Kenshin manga series by Nobuhiro Watsuki, and serving as the fourth installment of the Rurouni Kenshin film series following Rurouni Kenshin: The Legend Ends (2014). The film adapts the manga series' final arc, though some story elements differ. Like the previous entries, it was directed and written by Keishi Otomo, with Takeru Satoh reprising his role as Himura Kenshin. The film's story focuses on the arrival of Yukishiro Enishi as he seeks revenge against Kenshin for the death of his sister Yukishiro Tomoe, which leads to a confrontation between the two.

Rurouni Kenshin: The Final was released in Japan on April 23, 2021, by Warner Bros. Pictures Japan, and released later internationally on Netflix. It received positive reviews from critics. The film was produced simultaneously alongside the film series' fifth and final installment Rurouni Kenshin: The Beginning, a prequel whose footage is used in flashback scenes in The Final, which released two months later.
