Vengeance (2011) was a professional wrestling pay-per-view (PPV) event produced by WWE that took place on October 23, 2011 at the AT&T Center in San Antonio, Texas. It is the twelfth event under the Vengeance/Night of Champions chronology and the first event under the Vengeance name since the 2007 edition. Eight matches took place at the event. The pay-per-view garnered 121,000 buys, down from 137,000 buys the previous year's event, Bragging Rights, received.

The main rivalry from Raw involved WWE Champion Alberto Del Rio against former champion John Cena for the WWE Championship. At Hell in a Cell earlier in the month, John Cena lost his title to Alberto Del Rio after John Cena was locked out of the steel cell while Alberto Del Rio pinned CM Punk. A week later, recently instated Interim General Manager of Raw John Laurinaitis booked John Cena's rematch against Alberto Del Rio for Vengeance. On the October 17 episode of Raw, John Cena won a tag team match with Jim Ross to defeat Alberto Del Rio and Michael Cole and as per the pre-match stipulation, he chose the match at Vengeance to be a Last Man Standing Match.

Another rivalry from Raw was between CM Punk, Triple H, The Miz, and R Truth. At Night of Champions 2011, during the main event which was between the COO Triple H and Punk, Miz and Truth interfered and attacked both competitors. The following night on Raw, Triple H fired Miz and Truth. At Hell in a Cell, Miz and Truth attacked John Cena, CM Punk, Alberto Del Rio, the referee, and cameramen while the cell was still closed. The entire WWE roster came out to find a way into the cell. Eventually, they found pliers and got into the cell and Triple H attacked Miz and Truth. On the October 10th edition of Raw, Triple H was relieved from his duties of running Monday Night RAW (though still COO) and Executive Vice President of Talent Relations John Laurinaitis was named Interim General Manager Of Raw and later that night made this match.
