Mystery Ranch is a 1934 American comedy Western film co-produced and directed by Bernard B. Ray and starring Tom Tyler, Roberta Gale and Jack Perrin.

Pulp Western writer Bob Morris is invited to a dude ranch whose owner Mrs. Henderson promises will feature the "real" dangerous Wild West.

In reality Mrs. Henderson arranges a variety of fake lynchings, cattle rustling and dangerous situations to frighten Mr. Morris and gain publicity for her ranch.

The joke backfires because Morris is a skilled horseman and expert fighter who impresses Mrs. Henderson and her daughter Mary.

In reality it is an actual holdup of gold bullion with the robbers coming to Mrs. Henderson's ranch.
