Waterworld is a 1995 American post-apocalyptic science fiction action film directed by Kevin Reynolds and co-written by Peter Rader and David Twohy. It was based on Rader's original 1986 screenplay and stars Kevin Costner and Dennis Hopper, who also produced it with Charles Gordon and John Davis. It was distributed by Universal Pictures.

The setting of the film is in the distant future. Although no exact date was given in the film itself, it has been suggested that it takes place in 2500. The polar ice caps have completely melted, and the sea level has risen over 7,600 m (25,000 feet), covering nearly all of the land. The remaining people travel the seas, in search of survival. Several different societies exist. The Mariner (Kevin Costner) falls from his customary and solitary existence into having to care for a woman and a young girl while being pursued by the evil forces of a bunch of pirates led by the Deacon (Dennis Hopper).
