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 live-action film based on the manga series of the same name by Nobuhiro Watsuki 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. The film was produced simultaneously alongside the film series' fifth and final installment Rurouni Kenshin: The Beginning, which serves as a direct prequel to The Final, with flashback scenes being taken from The Beginning. Like previous movies, it was directed and written by Keishi Otomo.

The movie features the talents of Takeru Satoh, Emi Takei, Mackenyu Arata, Yusuke Iseya, Munetaka Aoki, Yū Aoi, Tao Tsuchiya, Ryunosuke Kamiki and Yōsuke Eguchi. The movie focuses on the Shangai mafia leader Yukishiro Enishi as he arranges multiple terrorist attacks to torment the former assassin Himura Kenshin as a revenge for killing his sister Yukishiro Tomoe during the Bakumatsu period. This leads to the eventual confrontation between the two lead and their allies. The movie is licensed by Netflix.

The movie was well received in the box office to the point it was one of the highest-grossing films in 2021. Critics praised the narrative focused on Kenshin's quest for redemption and his rivalry with the menacing Enishi. Although the plot has several changes to the original manga, it was noted to be true to the source's themes. The performances of Satoh and Mackenyu were praised, as were the choreographed fight scenes.
