Space Ghost is an American Saturday-morning superhero animated television series produced by Hanna-Barbera Productions, first broadcast on CBS from September 10, 1966, to September 16, 1967, and continued reruns until September 7, 1968. The series was composed of two unrelated segments, Space Ghost and Dino Boy in the Lost Valley. The series was created by Alex Toth and produced and directed by William Hanna and Joseph Barbera. Sometimes, it is alternatively called Space Ghost & Dino Boy to acknowledge the presence of both shows.

The Space Ghost segments were seen again in the 1976 series Space Ghost and Frankenstein Jr. (which replaced the Dino Boy segments with the Frankenstein Jr. ones from fellow Hanna-Barbera show Frankenstein Jr. and The Impossibles), which aired on NBC from November 27, 1976, to September 4, 1977, after NBC put The Kids From C.A.P.E.R. on hiatus.
