Sigmund and the Sea Monsters was a children's television series that ran from 1973 to 1975. The show was a Sid and Marty Krofft production and was shown on Saturday mornings. There were 29 episodes spanning two seasons.

Its basic premise was that Sigmund (Billy Barty), a friendly (if somewhat cowardly) sea monster who runs away from his comically dysfunctional undersea family, is discovered and befriended by brothers Johnny (Johnny Whitaker) and Scott Stuart (Scott Kolden), who let Sigmund stay in their hideout.
