Thunder Over Texas is a 1934 American populist contemporary Western film directed by Edgar G. Ulmer under the alias Joen Warner (the name of Ulmer's previous wife) and produced by two nephews of Universal Pictures head Carl Laemmle, Arthur and Max Alexander's Poverty Row Beacon Productions. The film's story was written by Shirley Ulmer under the name of Sherle Castle. Shirley was then married to Max Alexander but would soon leave Max to marry Edgar with the result that Lammele blacklisted Ulmer from Hollywood. The film was shot in Kernville, California.

Thunder Over Texas was the first of several Westerns produced by the Alexanders starring Guinn "Big Boy" Williams.
