Rexy is the colloquial nickname for a fictional Tyrannosaurus that appears throughout the Jurassic Park franchise. It first appeared in Michael Crichton's 1990 novel Jurassic Park, and made it onscreen debut in the 1993 film adaptation, directed by Steven Spielberg. It returns in the 2015 film Jurassic World and its sequels, Jurassic World: Fallen Kingdom (2018) and Jurassic World Dominion (2022).
For the original film, special-effects artist Stan Winston created an animatronic T. rex measuring 20 feet high and 40 feet long, while Steve Williams of Industrial Light & Magic (ILM) created a CGI version for a majority of the scenes. Colin Trevorrow served as the primary writer and director of the Jurassic World trilogy. Although other T. rexes appeared in the preceding Jurassic Park sequels, Trevorrow sought to bring back the same individual from the first film. ILM again worked on the animal for each of the Jurassic World films. Effects artist Neal Scanlan also created an animatronic for Fallen Kingdom.
The films do not specify a name for the animal. "Rexy" came into common usage among fans after the release of Jurassic World, although the name had also been used previously in Crichton's novel. It has since been used in other licensed media. The name "Roberta" was also used by visual-effects artist Phil Tippett in his storyboards for the original film.
