The Quick Gun is a 1964 American Techniscope Western film directed by Sidney Salkow and starring Audie Murphy. It was the second of four films produced by Grant Whytock and Edward Small's Admiral Pictures in the 1960s.

The film's screenplay was based on Steve Fisher's short story The Fastest Gun that had previously provided the story for two other Westerns, Top Gun (1955) starring Sterling Hayden and Noose for a Gunman (1960) starring Jim Davis and Ted de Corsia as the villain, both for United Artists. Fisher at this time was also providing the screenplays for a series of A.C. Lyles's second-feature Techniscope Westerns for Paramount Pictures.
