The No Mercy Man (also known as Bad Man, Trained to Kill, and Trained to Kill USA) is a 1973 action film with elements of a modern-day Western starring Steve Sandor, Rockne Tarkington, Sid Haig, Ron Thompson, Mike Lane, and Richard X. Slattery. The film was co-written (with Michael Nolin) and directed by Daniel Vance in his first and last feature film. The film was shot in Todd-AO by Dean Cundey in his first feature film with Buddy Joe Hooker arranging the stunt work and acting as second unit director. Master Jerry Druckerman acted as the film's martial arts technical advisor.

Film director Quentin Tarantino programmed The No Mercy Man as part of a March 2011 revenge film triple feature at the New Beverly Cinema, which Tarantino took over in March 2007.
