This Is Your FBI was a radio crime drama that aired on ABC from April 6, 1945, to January 30, 1953, totaling 409 episodes. The show was endorsed by FBI chief J. Edgar Hoover and was based on true cases from the FBI told from an agent's perspective. The episodes covered everything from crackdowns on organized crime to stories of individual lawbreakers, with cases involving fraud, petty crime, and professional criminals.

The show initially featured a fictitious agent, Jim Taylor, played by Stacy Harris. Producer-director Jerry Devine was given access to FBI closed case files by Hoover to dramatize the stories, and the narration was handled by Frank Lovejoy, Dean Carleton, and William Woodson. The cast included famous stars like Betty White, William Conrad, Herb Ellis, and many others.

This Is Your FBI was sponsored by the Equitable Life Assurance Society of the United States and is considered a pioneer in authentic crime-drama storytelling. The show laid the foundation for later crime dramas such as Dragnet and Tales of the Texas Rangers.
