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.

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 playing on the beach near Dead Man's Point, the two of them discover a friendly young sea monster named Sigmund who had been thrown out by his comically dysfunctional undersea family for refusing to frighten people.

A cover of the show's theme song, performed by Tripping Daisy, is included on the 1995 tribute album Saturday Morning: Cartoons' Greatest Hits, produced by Ralph Sall for MCA Records.

Eleven songs from the show were released on Johnny Whitaker's album Friends (Music from the Television Series 'Sigmund and the Sea Monsters') (Chelsea Records, BCL1-0332).

In the United States, the first season of the show was released on DVD in 2005 by Rhino Entertainment, featuring all 17 original broadcast episodes, uncut and digitally remastered.

In 2015 Sid and Marty Krofft announced that Amazon was partnering with them to create an updated version of Sigmund and the Sea Monsters.

In this version of the series, David Arquette plays Captain Barnabus who believes sea monsters are real and devotes his life to capturing them.
