Rancho Grande is a 1940 American Western film directed by Frank McDonald and starring Gene Autry, Smiley Burnette, and June Storey.

Gene is also responsible for completing a major project started by Dodge—the construction of an irrigation system that would bring valuable water to the faithful Rancho Grande employees in the southern part of the valley.

When Dodge's grandchildren, Tom (Dick Hogan), Kay (June Storey), and Patsy (Mary Lee), arrive from the east, they are unimpressed with life on the ranch.

After meeting Tom and Kay, he decides to take advantage of their discontent in order to slow the irrigation project and prevent the bank from renewing the mortgage.

In the gunfight that ensues, Gene captures Benson and his gang, insuring the timely completion of the irrigation project and the grandchildren's continued ownership of Rancho Grande.
