This Is Your FBI was a radio crime drama that featured true cases from the Federal Bureau of Investigation (FBI), as seen from an agent's perspective. FBI Chief J. Edgar Hoover endorsed the show, calling it "the finest dramatic program on the air." The series included stories of crackdowns on organized crime, individual lawbreakers, and false accusations. Each episode alternated between the criminals' actions and the agents' accounts of the investigations. The show highlighted the FBI's latest methods and techniques through the dramatization of its closed case files, with narration provided by Frank Lovejoy, Dean Carleton, and William Woodson.

The series was broadcast on ABC from April 6, 1945, to January 30, 1953, airing a total of 409 episodes. Hoover granted producer-director Jerry Devine access to FBI files for the series, and the cast included Stacy Harris, Betty White, William Conrad, Herb Ellis, Michael Ann Barrett, Carleton Young, Georgia Ellis, Jay C. Flippen, and more. Other radio dramas that also focused on crime investigations include Gangbusters, Mr. District Attorney, and The FBI in Peace and War. This Is Your FBI was sponsored by the Equitable Life Assurance Society of the United States throughout its entire run.
