Fantastic Planet is a 1973 surrealist adult animated science fiction art film directed by René Laloux. It's an allegorical story about humans living on a strange planet dominated by giant humanoid aliens who consider them animals, based on the 1957 novel Oms en série by the French writer Stefan Wul. The film was written by Laloux and Roland Topor; the latter also made the production design. It was a co-production between companies from France and Czechoslovakia and was animated at Jiří Trnka Studio in Prague.

Fantastic Planet was awarded the Grand Prix special jury prize at the 1973 Cannes Film Festival, and in 2016, it was ranked the 36th greatest animated movie ever by Rolling Stone.
