Samurai Trilogy is a trilogy of three movies directed by Hiroshi Inagaki and starred in by Toshiro Mifune as Miyamoto Musashi. The films are based on the novel by Eiji Yoshikawa, about Miyamoto Musashi, famous duellist and author of The Book of Five Rings. The film is regarded as a classic of Japanese cinema, and is sometimes called the "Gone with the Wind of Japan".

The first film is Samurai I aka Miyamoto Musashi and is from 1954. The second film is Samurai II aka Duel at Ichijoji Temple and is from 1955. The third film is Samurai III aka Duel on Ganryu Island and is from 1956. Together, this is a trilogy of epic proportions following the character growth of Musashi from brash - yet strong - young soldier to thoughtful and introspective samurai.

It is noteworthy that the trilogy also became an influence for future films. In Kill Bill, for example, the Bride kills O-Ren Ishii with the exact same swallows tail move that Musashi uses to kill Kojiro, the filming for this scene is almost identical as well with the same parrelel run, blood splash, and unknown victor until the faces are revealed.
