Creation Entertainment is an American for-profit entertainment company located in Glendale, California, which produces fan conventions for fans of various films and television series, mainly in the science fiction, horror, and fantasy genres. Creation Entertainment hosts about 20 conventions annually in various locations such as Chicago, Illinois; and Burbank, California. Creation was founded in 1971 by comic book fans Gary Berman and Adam Malin in New York City. Since then, it has organized over 2,300 conventions.

Creation hosts the largest Star Trek convention in the world, which occurs annually during the summer in Las Vegas, Nevada; they previously produced Fangoria's Weekend of Horrors conventions. The company has the "official" convention rights for such properties as Twilight, Stargate SG-1, and Xena: Warrior Princess. The company is also a licensee of merchandise for many genre television series, including The X-Files, Xena, Stargate SG-1, Stargate Atlantis, Lost and Supernatural, producing souvenir items such as T-shirts, hats, mugs, autographed items and calendars.

Creation conventions consist of on-stage celebrity appearances, Q&A sessions, parties and cabaret performances featuring celebrities and charity auction breakfasts. Attendees may also purchase autographs and photo ops that allow fans to be photographed with celebrities.

Creation collects additional money at their shows through limited-attendance functions not included in the ticket prices, including celebrity food functions, photo opportunities, and slower-paced autographing sessions.
