The 2001 Judgment Day was the third Judgment Day professional wrestling pay-per-view (PPV) event produced by the World Wrestling Federation. 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.

ARCO Arena was an indoor arena located in Sacramento, California, United States. Opened in 1988, it was the home of the Sacramento Kings of the National Basketball Association (NBA) from 1988 to 2016. It hosted nearly 200 spectator events each year. The arena was named for ARCO, at the time in 1988, a Los Angeles-based independent oil and gas company that today is now a brand owned by Findlay, Ohio-based Marathon Petroleum. It was later named for Sleep Train, a chain of mattress and bed retailers based in Rocklin, California, that at the time of the agreement was a subsidiary of Mattress Firm, a Houston-based retailer that has since re-branded all Sleep Train stores as Mattress Firm. Several major entertainers have performed at the venue before its closure including Bruno Mars and Linkin Park.
