Laff-A-Lympics is an American animated comedy television series produced by Hanna-Barbera. The series premiered as part of the Saturday-morning cartoon program block Scooby's All-Star Laff-A-Lympics which consists of 24 episodes, on ABC in 1977. The show is a spoof of the Olympics and the ABC primetime series Battle of the Network Stars, which debuted one year earlier. It featured 45 Hanna-Barbera characters organized into teams (the Scooby Doobies, the Yogi Yahooeys, and the Really Rottens) which competed each week for gold, silver, and bronze medals. In each episode, the Really Rottens would try in each event to cheat only to get caught by Snagglepuss each time. 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. Scooby’s Laff-a-Lympics was originally owned by Taft Broadcasting, Warner Bros. Domestic Television Distribution currently owns the series through its two in-name-only units, Warner Bros. Family Entertainment and Turner Entertainment.

The "all-star" cast was mostly made up of characters from other Hanna-Barbera series. The "Scooby Doobies" included characters from Scooby-Doo, Where Are You!, Captain Caveman and the Teen Angels, Speed Buggy and Dynomutt, Dog Wonder; the "Yogi Yahooeys" had characters from The Yogi Bear Show, The Huckleberry Hound Show and The Quick Draw McGraw Show. The only original characters were some members of the Really Rottens.In 1978, Hanna-Barbera produced another "all-star" show with a similar theme, titled Yogi's Space Race.
