Pufnstuf is a 1970 American comedy fantasy musical film produced by Sid and Marty Krofft Enterprises and released by Universal Pictures. It is based on the children's television series H.R. Pufnstuf, a show that features a cast of puppets on a "living island."

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.
