The Millennium Group is a fictional secret society featured in the crime thriller television series Millennium. Having begun life as a Christian sect at the end of the 1st century AD, the Group grew into a far-reaching network which, as the 3rd millennium approached, presented itself as a private investigative firm liaising with law enforcement organizations. Despite being fraught with internal schisms, the Group tried on several occasions to artificially instigate the end of the world as the year 2000 approached.
