Yojimbo (Japanese: 用心棒, Hepburn: Yōjinbō, lit. Bodyguard) is a 1961 Japanese samurai film directed by Akira Kurosawa, who also co-wrote the screenplay and was one of the producers. The film stars Toshiro Mifune, Tatsuya Nakadai, Yoko Tsukasa, Isuzu Yamada, Daisuke Katō, Takashi Shimura, Kamatari Fujiwara, and Atsushi Watanabe. In the film, a rōnin arrives in a small town where competing crime lords fight for supremacy. The two bosses each try to hire the newcomer as a bodyguard.

Based on the success of Yojimbo, Kurosawa's next film, Sanjuro (1962), was altered to incorporate the lead character of this film. In both films, the character wears a rather dilapidated dark kimono bearing the same family mon.

The film was released and produced by Toho on April 25, 1961. Yojimbo received highly positive reviews, and, over the years, became widely regarded as one of the best films by Kurosawa and one of the greatest films ever made. The film grossed an estimated US$2.5 million worldwide with a budget of ¥90.87 million ($631,000). It was unofficially remade by Sergio Leone as the Spaghetti Western film A Fistful of Dollars (1964), leading to a lawsuit by Toho.
