The Winning of Barbara Worth is a 1926 American silent Western film directed by Henry King, and starring Ronald Colman, Vilma Bánky and Gary Cooper (who replaced Monte Blue).

Based on Harold Bell Wright's novel The Winning of Barbara Worth, the film is remembered for the climactic flood sequence, depicting the 1905 formation of the Salton Sea.

Fifteen years later, Willard Holmes, the chief engineer of a company intent on diverting the Colorado River to do just that, arrives and is smitten with Barbara.

Willard Holmes's greedy employer, meanwhile, refuses to spend the money to reinforce his gigantic water project.

Barbara is impressed by Willard's heroism, and he promises to return to marry her after he has conquered the Colorado River and turned the desert into a bountiful paradise.
