Arch Oboler's Plays was a radio anthology series that aired on NBC Radio from March 25, 1939, to March 23, 1940, and was later revived on Mutual from April 5 to October 11, 1945. Created, written, produced, and directed by Arch Oboler, the show featured original works of fiction that explored the human psyche and were known for their stream-of-consciousness technique. The series was the first to have a writer's name in the title, paving the way for radio as an art form. The show boasted a stellar lineup of leading film actors, such as Ingrid Bergman, James Cagney, Katharine Hepburn, and Peter Lorre.

Oboler, known for his eccentric personality and innovative storytelling techniques, gained popularity for his work on Lights Out which experimented with sound effects and bold narratives that sparked controversies. In his venture, Arch Oboler's Plays, he used some of his scripts in his later series, Everyman's Theater. As a staunch anti-Nazi, he also included anti-Fascist themes in his work, especially during World War II.

In 2020, the November 18, 1939 episode "The Bathysphere" was added to the Library of Congress' National Recording Registry for its cultural, historical, and aesthetic importance.
