WrestleMania XXVI was the twenty-sixth annual WrestleMania professional wrestling pay-per-view event produced by World Wrestling Entertainment (WWE), which took place on March 28, 2010, at the University of Phoenix Stadium in the Phoenix suburb of Glendale, Arizona. This was the first WrestleMania since WrestleMania XI with a non-title match as a main event, the first WrestleMania to be held in the state of Arizona and the third to be held in an open-air venue, after WrestleMania IX and WrestleMania XXIV.

WrestleMania XXVI was a joint-promotion event, with performers both from the Raw and SmackDown brands. The event's card consisted of eight matches, including three main matches. The first of these matches was a no disqualification, no countout match, in which The Undertaker defeated Shawn Michaels to improve his undefeated WrestleMania streak to 18–0. Per the pre-match stipulation, Michaels was forced to retire. The second was a singles match for the WWE Championship that saw John Cena defeat Batista to win the championship. The third saw World Heavyweight Champion Chris Jericho defeat the 2010 Royal Rumble winner Edge to retain the title. The undercard also included a No Holds Barred match between Bret Hart and Mr. McMahon and the sixth annual Money in the Bank ladder match.
