The Alcazar Theatre was a 1,145 seat theatre located at 260 O'Farrell Street, San Francisco, California, built in 1911 by architects Cunningham and Politeo, replacing the previous Alcazar Theatre one block to the east, which was destroyed in the 1906 San Francisco earthquake fire. This venue soon became one of San Francisco's leading legitimate theatres offering a wide range of productions, and like its predecessor, also housed a popular resident stock company.
