The 2009 Judgment Day was the 11th and final Judgment Day professional wrestling pay-per-view (PPV) event produced by World Wrestling Entertainment (WWE). It was held for wrestlers from the promotion's Raw, SmackDown, and ECW brand divisions. The event took place on May 17, 2009, at the Allstate Arena in the Chicago suburb of Rosemont, Illinois. Judgment Day was replaced by Over the Limit in 2010.

The event's card featured seven matches. The main event for the show saw Edge successfully defend SmackDown's World Heavyweight Championship against Jeff Hardy. In Raw's main match, WWE Champion Randy Orton was disqualified in a match against Batista and therefore retained as titles do not change hands via disqualification unless stipulated. In addition, John Cena defeated Big Show. The undercard for the show had four other singles matches: CM Punk versus Umaga, ECW Champion Christian defending the championship against Jack Swagger, John Morrison versus Shelton Benjamin, and Rey Mysterio defending SmackDown's Intercontinental Championship against Chris Jericho.

The event had 228,000 buys, down from the Judgment Day 2008 figure of 252,000 buys.
