The Omega Code is a 1999 apocalyptic thriller film directed by Rob Marcarelli, written by Stephen Blinn and Hollis Barton, and starring Casper Van Dien, Michael York, Catherine Oxenberg and Michael Ironside. The premillennialist plot revolves around a plan by the Antichrist (York) to take over the world by using information hidden in the titular Bible code.

The independently produced film was financed and distributed by the Trinity Broadcasting Network, whose head, televangelist Paul Crouch, wrote a novelization of the film's screenplay. The film received a limited theaterical release in the United States on October 15, 1999, grossing $12 million against a $7.2 million budget, before being released on home video by GoodTimes Entertainment.

In 2001, the film had a sequel entitled Megiddo: The Omega Code 2, which serves partly as a prequel as well as an alternate retelling of the first film's eschatological plot. While it had a significantly larger budget than the original, it was less enthusiastically received, and was ultimately less popular.
