Sigmund and the Sea Monsters is an American children's television series that ran from September 8, 1973, to October 18, 1975, produced by Sid and Marty Krofft and aired on Saturday mornings. It was syndicated by itself from December 1975 to June 1978 and later as part of the Krofft Superstars show from 1978 to 1985.

The episodes included songs as part of the plot development. The character(s), generally Johnny, would sing a song about what he was thinking or feeling about something going on in his life, from things that made him happy to anxiety about girls.

While videotaping the first episode of Season Two, a hot light fell and started a fire. No one was injured, but the fire destroyed all of the sets and much of the costumes and other props. Most of Season Two was taped with minimal sets.
