Captain Video and His Video Rangers is an American science fiction television series that aired on the DuMont Television Network and was the first series of its genre on American television.

The series aired between June 27, 1949, and April 1, 1955, originally on Monday through Saturday at 7 p.m. ET, and then Monday through Friday at 7 p.m. ET. A separate 30-minute spinoff series called The Secret Files of Captain Video aired Saturday mornings, alternating with Tom Corbett, Space Cadet, from September 5, 1953, to May 29, 1954, a total of 20 episodes.Researcher Alan Morton estimates there were a total of 1,537 episodes (not counting the 20 Saturday morning episodes), although few of them exist after the destruction of the original broadcasts, which was commonplace at that time. Sponsors included Post Cereals, Skippy Peanut Butter, DuMont-brand television sets, and Peter Paul's PowerHouse candy bars. Premiums sold via the show included a flying saucer ring, a "secret seal" ring, cast photos, electronic goggles, a "secret ray gun", a rocket ship key chain, decoders, membership cards, and a set of 12 plastic spacemen.
