Beau Sabreur is a 1928 American silent romantic adventure film directed by John Waters and starring Gary Cooper and Evelyn Brent. Due to the public apathy towards silent films, a sound version was also prepared. While the sound version has no audible dialog, it was released with a synchronized musical score with sound effects using both the sound-on-disc and sound-on-film process. Based on the 1926 novel Beau Sabreur by P. C. Wren, who also wrote the 1924 novel Beau Geste. Produced by Paramount Famous Lasky Corporation and distributed by Paramount Pictures, only a trailer exists of this film today. The released feature version is a lost film.

In the original novel the lead character Major Henri de Beaujolais is an officer of spahis (Algerian colonial cavalry of the French Army) and has no connection with the better known Foreign Legion. In all surviving stills of Beau Sabreur Gary Cooper is shown wearing the distinctive spahi uniform and it is not clear whether the lost film was intended to be a Foreign Legion epic.
