Actors Studio is an American television series that was hosted by Marc Connelly. It originally aired on ABC from September 26, 1948 to October 26, 1949 and then on CBS from November 1, 1949, to June 23, 1950. It was one of the first series to be picked up by a network after being cancelled by another network. CBS departed from its own precedent when it took the World Video-owned series. Until then it had not shown any sustaining programs that were not owned (at least partially) by CBS.

The series showcased short pieces of adapted, classic and original drama, performed and produced live each week from New York. Among some of the known authors were William Saroyan, James Thurber, Ring Lardner, Edgar Allan Poe, Irwin Shaw and Budd Schulberg. Featured actors included Martin Balsam, Richard Boone, Marlon Brando, Hume Cronyn, Julie Harris, Jean Muir and Jessica Tandy. Recurring performers included Jocelyn Brando, Tom Ewell, Steven Hill, Kim Hunter and Cloris Leachman.

In February 1950, the series moved to Friday nights and was expanded to one hour, alternating every other week with broadcasts of Ford Theatre. In March, the name of the show was changed to The Play's the Thing.

The series received a Peabody Award in 1949, being cited for its "outstanding contribution to the art of television". Henry S. White of World Video Inc. produced the series, and Donald Davis was the director. It originated from WCBS-TV.

The series had no sponsors, which led to a reduction in funds available for purchasing rights to properties for adaptation. The result of that change was a shift from "well-known one-act plays" to short stories".
