DuMont Royal Theater (also known as Royal Playhouse) is an American dramatic anthology television series which ran on the now-defunct DuMont Television Network from April 12, 1951, to June 26, 1952. The half-hour series ran during the summers, and in 1952 it ran on alternate weeks with Gruen Playhouse. The series helped launch the career of Hugh O'Brian, who later appeared in the popular series The Life and Legend of Wyatt Earp. Others who appeared on the program included Mary Sinclair and Edgar Barrier. Some sources say the sponsor was when it was part of Standard Brands.
