666 Park Avenue is an American supernatural drama television series that aired on ABC from September 30, 2012, to July 13, 2013. The series was developed and produced by David Wilcox, and was loosely based upon the novel of the same name by author Gabriella Pierce. The show stars Rachael Taylor, Dave Annable, Vanessa Williams, and Terry O'Quinn and follows a couple who learns that the Manhattan apartment building that they just moved into, including its upscale tenants, might be possessed by a mysterious demonic force.

The elaborate Beaux-Arts building located on the old money Upper East Side of Manhattan called "The Drake" in the series is an actual apartment building, The Ansonia in Upper West Side.

ABC ordered the pilot on January 20, 2012, and it was picked up for a full season of 13 episodes on May 11, 2012 (2012-05-11). It aired on Sunday evenings at 10:00 pm Eastern/9:00 pm Central, with the series Revenge serving as its lead in. On November 16, 2012, after the seventh episode aired, ABC announced that the series had been canceled, but that it would finish its 13-episode run.

On December 21, 2012, after the ninth episode aired, ABC announced that the series had been removed from its schedule, with the remaining four episodes to be burned off in the dead of the summer 2013 schedule. The original time slot was taken by Happy Endings and Don't Trust the B---- in Apartment 23. The final four episodes were first broadcast in Spain, then aired in Australia, New Zealand and the United Kingdom, before airing in the United States from June 22 to July 13, 2013.
