Tonto Basin Outlaws is a 1941 American western film directed by S. Roy Luby.

The film is the tenth in Monogram Pictures' "Range Busters" series, and it stars Ray "Crash" Corrigan as Crash, John "Dusty" King as Dusty and Max "Alibi" Terhune as Alibi, with Jan Wiley, Tris Coffin and Edmund Cobb.

Like the other of the Range Busters series, the film was shot at Corriganville Movie Ranch and used footage from silent Westerns.

They are disappointed they are to be mustered out due to Crash's familiarity with Montana in order to protect cattle herds and gold shipments meant for the Army that are being attacked.

Working undercover in a Montana saloon owned by town boss Jeff Miller, Jane suspects first Crash, then Rusty of being one of the rustlers.
