Sundance is a town in Crook County, Wyoming, United States. The population was 1,161 at the 2000 census. The town is named for the Sun Dance ceremony practiced by several North American Indian Nations.
After his release from the Sundance Jail in 1888, Harry Longabaugh acquired the moniker the Sundance Kid, which entered the popular imagination in the 1969 movie Butch Cassidy and the Sundance Kid, which won several Academy Awards including Best Original Screenplay. Robert Redford, who portrayed Longabaugh in the movie, later named the Sundance Ski Resort, near Provo, Utah, and the Sundance Film Festival after this character. A sign visible from I-90 proclaims that Sundance is "where the kid got his name."
