Behind Closed Doors is an American drama series set during the Cold War hosted by and occasionally starring Bruce Gordon in the role of Commander Matson. The series, which aired on NBC from October 2, 1958, to April 9, 1959, focuses, among other themes, on how the former Soviet Union stole American missile secrets and proposes steps to prevent further espionage. Behind Closed Doors is based on the files and experiences of Rear Admiral Ellis M. Zacharias, who offers comments at the end of each segment.

Behind Closed Doors, a Screen Gems production, replaced Jackie Cooper's sitcom The People's Choice, followed the NBC quiz show, Twenty-One, and preceded the The Tennessee Ernie Ford Show. Its competition was The Pat Boone Chevy Show on ABC and Dick Powell's Zane Grey Theater western anthology series on CBS.
