Rancho Grande is a 1940 American Western film directed by Frank McDonald and starring Gene Autry, Smiley Burnette, and June Storey. Written by Bradford Ropes, Betty Burbridge, and Peter Milne, based on a story by Peter Milne and Connie Lee, the film is about a singing cowboy and ranch foreman responsible for completing an important irrigation project and for the three spoiled grandchildren of his former boss who come out West to the ranch they inherited.

Lester Alvin Burnett, better known as Smiley Burnette, was an American country music performer and a comedic actor in Western films and on radio and TV, playing sidekick to Gene Autry, Roy Rogers, and other B-movie cowboys. He was also a prolific singer-songwriter who is reported to have played proficiently over 100 musical instruments, sometimes more than one simultaneously. His career, beginning in 1934, spanned four decades, including a regular role on CBS-TV's Petticoat Junction in the 1960s.
