Sealab 2020 is an American animated television series produced by Hanna-Barbera Productions and broadcast on NBC from September 9 to December 2, 1972, on Saturday mornings. The series was created by Alex Toth, who also created such other Hanna-Barbera cartoons as "Space Ghost" and "Birdman and the Galaxy Trio".

As with most Hanna-Barbera series, the show was in occasional rotation on Boomerang, the TV channel that owns the Hanna-Barbera archives. From 2000 to 2005, the series had returned for a second life when it was parodied as "Sealab 2021" on Cartoon Network's Adult Swim.
