The 2007 Backlash was the ninth 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 29, 2007, at the Philips Arena in Atlanta, Georgia. It was WWE's first monthly PPV held to feature all three brands after the company discontinued brand-exclusive PPVs. The concept of the pay-per-view was based around the backlash from WrestleMania 23.

The main match on the Raw brand was a fatal four-way match for the WWE Championship involving champion John Cena, Randy Orton, Edge, and Shawn Michaels. Cena won the match and retained the championship after pinning Orton. The primary match on the SmackDown! brand was a Last Man Standing match for the World Heavyweight Championship between The Undertaker and Batista, which ended in a no-contest after both men failed get to their feet before the referee counted to ten. The featured match on the ECW brand was Bobby Lashley versus Team McMahon (Umaga, Vince and Shane McMahon) in a handicap match for the ECW World Championship. Vince won the title and the match for his team after pinning Lashley.
