Trespasser is a 1998 action-adventure video game developed by DreamWorks Interactive and published by Electronic Arts for Microsoft Windows. The game serves as a sequel to the 1997 film The Lost World: Jurassic Park, taking place a year after the film's events. Players control Anne, the sole survivor of a plane crash that leaves her stranded on a remote island with genetically engineered dinosaurs. It features the voices of Minnie Driver as Anne and Richard Attenborough as John Hammond, reprising his role from the film series.

The game engine of Trespasser was advanced for its time and required a fast and powerful computer to adequately display the game's detailed graphics without pixelation artifacts. Upon release, the game received mixed to negative reviews and disappointed many critics, with GameSpot declaring it "the worst game of 1998". The mixed reception is believed to have been caused by rushing the development to reach the 1998 release date and the game's overly ambitious and advanced nature.
