ReGenesis is a Canadian science-fiction television series produced by The Movie Network and Movie Central in conjunction with Shaftesbury Films. The series, which ran for four seasons from 2004 to 2008, revolves around the scientists of NorBAC (North American Biotechnology Advisory Commission), a fictional organization with a lab based in the city of Toronto. The organization investigates problems of a scientific nature, such as bioterrorism, mysterious diseases, or radical changes in the environment throughout North America. NorBAC is headed by David Sandström (played by Peter Outerbridge), the chief scientist, and molecular biologist. Through this character, the show often addresses topical social, political, and ethical issues related to the science at hand.

Internationally it can be seen on FX in the United Kingdom, The Science Channel, Halogen TV, and in syndication at CW Plus in the United States, and FX Latin America in Mexico; as well as numerous broadcasters in Europe and Asia.
