Theodore Rex, also known as T. Rex, is a 1996 buddy cop science-fiction comedy film written and directed by Jonathan Betuel and starring Whoopi Goldberg. Though originally intended for theatrical release, the film went direct-to-video, and consequently became the most expensive direct-to-video film ever made at the time of its release.

The film was not well-received, and saw Whoopi Goldberg being nominated for Worst Actress at the 1996 Golden Raspberry Awards. It is the first direct-to-video movie to receive any sort of Razzie nomination.
