Six-String Samurai is a 1998 American post-apocalyptic action comedy film directed by Lance Mungia and starring Jeffrey Falcon and Justin McGuire. Brian Tyler composed the score for this film along with Red Elvises, the latter providing the majority of the soundtrack.

The film was greeted with a great deal of excitement when shown at Slamdance in 1998, winning the Slamdance awards for best editing and cinematography, and gathering extremely favorable reviews from influential alternative, cult and indie film publications such as Fangoria, Film Threat and Ain't It Cool News. It is billed as a "post-apocalyptic musical satire".

In a limited theatrical release the film ran for several months in a few theaters, gaining a reputation as a minor cult film; having a budget of $2,000,000, it only made a mere $124,494 at the box offices. An intended trilogy has been discussed but not yet realized, just like the predicted launching of the career of the film's star, Jeffrey Falcon, a martial artist who had appeared in several Hong Kong action movies in the 1980s and early 1990s. While Mungia made several music videos, he did not direct another feature until the 2005 film The Crow: Wicked Prayer.
