The 2008 Night of Champions was the second annual Night of Champions 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 June 29, 2008, at the American Airlines Center in Dallas, Texas. While it was the second Night of Champions event, it was the first to be promoted solely under the Night of Champions name as the first event was a cross-promotional event with Vengeance called Vengeance: Night of Champions; Night of Champions subsequently replaced Vengeance. As per the theme of the event, every match on the card was contested for one of WWE's eight then-active championships; three were won and five were retained.
