William H. Comstock (May 7, 1889 – September 23, 1961), known by his stage name Billy House, was an American vaudevillian, Broadway performer and feature film actor. After devoting most of his career to live performance, he moved to Hollywood where he became a supporting actor during the 1940s and 1950s. According to admirer Orson Welles, the name "Billy House" was likely an invention for use in burlesque theaters.
