The 2001 Judgment Day was the third Judgment Day professional wrestling pay-per-view (PPV) event produced by the World Wrestling Federation (WWF, now WWE). It was sponsored by RC Cola. The event took place on May 20, 2001, at the ARCO Arena in Sacramento, California. It was the final Judgment Day promoted under the WWF name as the promotion was renamed to World Wrestling Entertainment (WWE) in May 2002, although early promotional material for that year's Judgment Day event still bore the WWF logo. It was also the last Judgment Day held before the introduction of the brand extension in March 2002, as well the last Judgement Day of the Attitude Era.

Seven professional wrestling matches were featured on the event's card. The main event was "Stone Cold" Steve Austin defending the WWF Championship against The Undertaker in a No Holds Barred match. The featured bouts on the undercard included Triple H defending the Intercontinental Championship against Kane in a Chain match, and a Two-out-of three falls match between Kurt Angle and Chris Benoit for Angle's 1996 Olympic Gold Medals.

The event grossed over $670,000 in ticket sales from an attendance of 13,623, which was higher than the previous year's event.
