Rurouni Kenshin (るろうに剣心 -明治剣客浪漫譚-, Rurōni Kenshin -Meiji Kenkaku Roman Tan-), sometimes called Samurai X, is a Japanese anime television series, based on the manga series of the same name by Nobuhiro Watsuki. It was directed by Kazuhiro Furuhashi, produced by SPE Visual Works and Fuji Television, and animated by Studio Gallop (episodes 1–66) and Studio Deen (episodes 67–95). It was broadcast on Fuji TV from January 1996 to September 1998. Besides an animated feature film, three series of original video animations (OVAs) were also produced; the first adapts stories from the manga that were not featured in the anime series; the second is both a retelling and a sequel to the anime series; and the third was a reimagining of the second story arc of the series.

Sony Pictures Television International produced its own English dub of the series, releasing it as Samurai X in Southeast Asia. Media Blasters later licensed the series in North America and released it on home video from 2000 to 2002. The series was aired in the United States on Cartoon Network's Toonami programming block in 2003, only broadcasting the first 62 episodes.

Rurouni Kenshin has ranked among the 100 most-watched series in Japan multiple times.

A second anime television series adaptation by Liden Films premiered in 2023 on Fuji TV's Noitamina programming block.
