Isla Sorna, alias Site B, is one island of the group The Five Deaths. A rather funny fact is that "Isla Sorna" means Sarcasm Island in Spanish. The research station of InGen, which created dinosaurs, was located on this island. It is the place where most of the movies, books and games about Jurassic Park take place.

Different versions of Isla Sorna exist in the different Jurassic Park canons:

• Isla Sorna (Novel canon)
• Isla Sorna (Movie canon)
• Isla Sorna (Trespasser canon)
• Isla Sorna (Jurassic Park Adventures canon)
