WWE (World Wrestling Entertainment) Vengeance is a professional wrestling pay-per-view (PPV) event produced by professional wrestling promotion WWE The inaugural event took place on December 9, 2001 and replaced WWE Armageddon for that year due to the possible insensitivity of the latter's name with respect to the September 11 attacks. The 2002 event featured the Raw and SmackDown! brands. The event was made exclusive to the SmackDown! brand in 2003 and in 2004 was made exclusive to the Raw brand. In 2007, following WrestleMania, all PPV events became tri-branded.

Vengeance took over WWF Fully Loaded's scheduled date in July 2002 and later moved to June in 2005, switching schedules with The Great American Bash. The 2007 event was promoted as Vengeance: Night of Champions and featured all WWE titles being defended. In 2008, the event dropped the Vengeance name and continued to promote as Night of Champions, later moving to September in 2010. After tentatively scheduling Night of Champions in 2011, the October-held WWE Bragging Rights was cancelled, being replaced by the event once again under the Vengeance name.
