Backlash (2005) was the seventh annual Backlash professional wrestling pay-per-view event produced by the World Wrestling Entertainment (WWE), which took place on May 1, 2005, at the Verizon Wireless Arena in Manchester, New Hampshire. It was presented by Namco's Tekken 5. The show's six matches showcased prominent WWE wrestlers, who acted out the franchise's stories in and out of the ring. The event starred talent from the Raw brand. To date, it is the only WWE pay-per-view event ever to be held in the state of New Hampshire.

In the main event, Batista defeated Triple H in a singles match to retain the World Heavyweight Championship. From the five scheduled bouts on the undercard, two received more promotion than the others. The first was a tag team match, in which Shawn Michaels and Hulk Hogan defeated Muhammad Hassan and Daivari. The other was a Last Man Standing match, a match where a wrestler is unable to respond to a ten count by the referee would lose. Edge defeated Chris Benoit after Benoit failed to get to his feet before the referee's count to ten.
