The Lost World: Jurassic Park is an action-adventure video game developed by Appaloosa Interactive, and published by Sega for the Sega Genesis and is based on the film of the same name, which in turn is based on the novel by Michael Crichton.

Unlike the previous Jurassic Park games for the Genesis, the game features a bird's-eye view perspective similar to Jurassic Park on the Super NES.

The player assumes the role of an unnamed character who must capture dinosaurs on Isla Sorna while stopping rival hunters from transporting dinosaurs to the mainland. The game consists of nineteen missions spread across four sections of the island, referred to as Sites One through Four. Boss levels must be played at the end of each Site in order to advance to the next Site.

A second player, in the role of Ian Malcolm, can help out in Cooperative Mode, or both players can work against each other in Competitive Mode. Weapons such as a taser, tranquilizer gun, shotgun and grenades can be used against hunters and dinosaurs. At times, the player can control vehicles such as an SUV and a hovercraft.
