Belle Starr is a 1941 American Western film loosely based on the life of 19th-century American outlaw Belle Starr, who gained notoriety for her criminal exploits and associations with prominent outlaws. The film stars Gene Tierney as Belle Starr and also features Randolph Scott, Dana Andrews, and Shepperd Strudwick. The film was directed by Irving Cummings and written by Lamar Trotti based on a story by Niven Busch and Cameron Rogers. It was produced by Kenneth Macgowan for 20th Century Fox and shot in Technicolor.

It was the first major Hollywood production to depict Starr, inspired by Cameron Rogers's 1927 article and subsequent book, Gallant Ladies. Development faced casting changes and production delays due to Gene Tierney's health issues, but the film's eventual success cemented its place among romanticized portrayals of the Old West.
