WWE Vengeance is an American professional wrestling pay-per-view (PPV) event that is produced by WWE, a professional wrestling promotion based in Connecticut. The event was created in 2001, when the promotion was still called the World Wrestling Federation (WWF). It initially replaced Armageddon for the promotion's December PPV due to sensitivity issues following the September 11 attacks. However, Armageddon would return the following year, with Vengeance moving up to July as a replacement for Fully Loaded. Following the promotion being renamed to WWE and the implementation of the brand extension in early 2002, the event was made exclusive to the SmackDown brand in 2003, and then Raw from 2004 to 2006 before WWE discontinued brand-exclusive pay-per-views.
