The 2008 Backlash was the 10th Backlash 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 April 27, 2008, at the 1st Mariner Arena in Baltimore, Maryland. The concept of the pay-per-view was based around the backlash from WrestleMania XXIV.

Eight professional wrestling matches were scheduled on the event's card, which featured a supercard, a scheduling of more than one main event. The first was a fatal four-way elimination match for the WWE Championship featuring wrestlers from the Raw brand, in which all four men fought in the ring at the same time, with competitors being eliminated by pinfall or submission. Triple H defeated WWE Champion Randy Orton, John Cena, and John "Bradshaw" Layfield (JBL) to win the championship. The other main event featured wrestlers from the SmackDown brand, in which defending World Heavyweight Champion The Undertaker defeated challenger Edge in a standard wrestling match, also known as a singles match. The main event from the ECW brand was a standard match in which defending ECW Champion Kane defeated challenger Chavo Guerrero. In addition, a featured bout was scheduled on the undercard, in which Shawn Michaels defeated Batista in a standard match.

Backlash had an attendance of approximately 11,277 and received 200,000 buys, less than the previous year's event. When the event was released on DVD, it reached a peak position of second on Billboard's Recreational Sports DVD Sales Chart. It was also the first Backlash PPV broadcast in high definition.
