Armstrong Circle Theatre is an American anthology drama television series which ran from 1950 to 1957 on NBC, and then until 1963 on CBS.  It alternated weekly with The U.S. Steel Hour.

The series featured original dramas by noted writers, although sometimes comedies were shown.  Its guidelines specifically called for the avoidance of violence.  Originally a half-hour production, in 1955 the show expanded to an hour and began to emphasize dramatized versions of real-life contemporary events (including the sinking of the SS Andrea Doria and a documentary on the history of Communism in the Soviet Union.  Upon moving to CBS, the show emphasized several Cold War topics, including espionage, Radio Free Europe and escapes from East Germany.  Rod Serling wrote two episodes of the program.  George Lowther was the producer for 62 episodes and wrote one.
