The Lost World: Jurassic Park is an action-adventure video game developed by DreamWorks Interactive and Appaloosa Interactive, and published by Electronic Arts and Sega for the Sony PlayStation and Sega Saturn, respectively, in 1997. The Lost World: Jurassic Park is based on the film of the same name, which in turn is based on the novel by Michael Crichton. In 1998 a special edition of the game was released for the Sony PlayStation as a Greatest Hits title and featured several modifications to the gameplay.

The Lost World: Jurassic Park ignores the plot of the film, despite featuring some of its dinosaurs and being set on "Site B", an island also known as Isla Sorna and used as InGen's dinosaur breeding site. The plot varies with every character, each one struggling to survive on the island, populated by over 20 species of dinosaurs in an environment of escalating chaos.
