Laff-A-Lympics is the co-headlining segment, with Scooby-Doo, of the package Saturday morning cartoon series Scooby's All-Star Laff-A-Lympics, produced by Hanna-Barbera Productions beginning in 1977. The show was a spoof of the Olympics and the ABC television series Battle of the Network Stars, which debuted one year earlier. It featured 45 Hanna-Barbera characters organized into the teams (the Scooby Doobies, the Yogi Yahooeys, and the Really Rottens) which would compete each week for gold, silver, and bronze medals. One season of 16 episodes was produced in 1977–78, and eight new episodes combined with reruns for the 1978–79 season as Scooby's All-Stars. Unlike most cartoon series produced by Hanna-Barbera in the 1970s, Laff-A-Lympics did not contain a laugh track.
