Planet of the Apes is an American science fiction media franchise consisting of films, books, television series and other media about a world where humans and intelligent apes clash for control. The series began with French author Pierre Boulle's 1963 novel La Planète des Singes, translated into English as both Planet of the Apes and Monkey Planet. The 1968 film adaptation, Planet of the Apes, was a critical and commercial success, initiating a series of sequels, tie-ins, and derivative works. Arthur P. Jacobs produced the series under APJAC Productions until his death in 1973; since then 20th Century Fox has owned the franchise.

Four sequels followed the original film between 1970 and 1973: Beneath the Planet of the Apes, Escape from the Planet of the Apes, Conquest of the Planet of the Apes, and Battle for the Planet of the Apes. The series also spawned two television series: Planet of the Apes in 1974 and the animated Return to the Planet of the Apes in 1975. Plans for a film remake stalled in "development hell" for over ten years before Tim Burton's Planet of the Apes was released in 2001. A new reboot film series commenced in 2011 with Rise of the Planet of the Apes, which was followed by Dawn of the Planet of the Apes in 2014; another sequel, titled War for the Planet of the Apes, is planned for a 2017 release. All of these versions have in turn led to other media and merchandising tie-ins, including books, comics, video games, and toys.
