In Your House 12: It's Time was the 12th In Your House professional wrestling pay-per-view (PPV) event produced by the World Wrestling Federation (WWF, now WWE) and presented by Milton Bradley's Karate Fighters. It took place on December 15, 1996, at the West Palm Beach Auditorium in West Palm Beach, Florida. The name of the show was taken from Vader's catchphrase and indicated that he was originally scheduled to have a high profile match on the show, but due to injuries, he was absent from the event.

The main event of the show was the first championship defense of newly crowned WWF Champion Sycho Sid, defending against former multi-time champion Bret Hart. The show featured five matches on the PPV portion, one match on the Free for All pre-show, and two dark matches. With the launch of the WWE Network in 2014, this show became available on demand, but it did not include the Free for All pre-show match.

This event featured technical broadcast difficulties during the show and those who ordered the event on DirecTV, Request TV and Viewer's Choice were allowed to watch the broadcast again days later.
