Sears Radio Theater was a radio drama anthology series that aired weeknights on CBS Radio in 1979 and was sponsored by the Sears chain. The show featured a different genre for each day of the week, including Western, Comedy, Mystery, Love and Hate, and Adventure nights. Luminaries such as Lorne Greene, Andy Griffith, Vincent Price, Cicely Tyson, Richard Widmark, Howard Duff, and Leonard Nimoy served as hosts.

In 1980, the show moved to the Mutual Broadcasting System and became the Mutual Radio Theater, which continued to air repeats from the CBS run, as well as a short season of new dramas. Sears stayed on as a sponsor during this time. The series was produced and directed by Fletcher Markle and Elliott Lewis, with theme music composed and conducted by Nelson Riddle. Sears Radio Theater featured many Golden Age radio actors and was an ambitious attempt to reinvigorate radio drama. The show ran until December 1981, and was the final radio drama series for Mutual.
