Far Out Space Nuts is a Sid and Marty Krofft children's television series that aired in 1975 for one season, and produced 15 episodes.

Sid Krofft and Marty Krofft, known as The Krofft Brothers and born as Cydus and Moshopopoulos Yolas, were a Canadian sibling team of television creators, writers and puppeteers. Through their production company, Sid & Marty Krofft Pictures, they made numerous children's television and variety show programs in the U.S., particularly in the 1970s, including H.R. Pufnstuf, Land of the Lost, and Sigmund and the Sea Monsters. Their fantasy programs often featured large-headed puppets, high-concept plots, and extensive use of low-budget special effects.
