Colorado Sunset is a 1939 American Western film directed by George Sherman and starring Gene Autry, Smiley Burnette, and June Storey.

Written by Betty Burbridge and Stanley Roberts, based on a story by Luci Ward and Jack Natteford, the film is about a singing cowboy and his buddies who discover that the ranch they bought is really a dairy farm—and worse, it's subject to intimidation from a protection racket that prevents dairy products from safely reaching the market.

When they arrive at the ranch purchased for them by Frog Millhouse (Smiley Burnette), they cannot believe that the herd consists of milkcows rather than the cattle they had anticipated.

The town veterinarian, Dr. Rodney Blair (Robert Barrat), suggests that the Hall Trucking Company is behind the raids and proposes the establishment of a protective association.

During the raid, Gene captures Clanton (Jack Ingram), one of Blair's men, and turns him over to Sheriff George Glenn (William Farnum).
