Studio One is an American anthology drama television series that was adapted from a radio series. It was created in 1947 by Canadian director Fletcher Markle, who came to CBS from the CBC. It premiered on November 7, 1948, and ended on September 29, 1958, with a total of 467 episodes over the course of 10 seasons.

An anthology series is a written series, radio, television, film, or video game series that presents a different story and a different set of characters in each different episode, season, segment, or short. These usually have a different cast in each episode, but several series in the past, such as Four Star Playhouse, employed a permanent troupe of character actors who would appear in a different drama each week. Some anthology series, such as Studio One, began on radio and then expanded to television.
