WrestleMania XXIV was the twenty-fourth annual WrestleMania professional wrestling pay-per-view event produced by World Wrestling Entertainment (WWE). The event took place on March 30, 2008, at the Florida Citrus Bowl in Orlando, Florida and was the first WrestleMania to be held in the state of Florida. WrestleMania XXIV was the second WrestleMania to be held outdoors, with the first being WrestleMania IX, held in Caesars Palace in Las Vegas, Nevada.

Nine professional wrestling matches were scheduled for the event, which featured a supercard, a scheduling of more than one main bout. The first of these matches was a Singles match from the SmackDown brand that featured The Undertaker defeating World Heavyweight Champion Edge to win the title. The second was a Triple Threat match from the Raw brand, in which WWE Champion Randy Orton defeated challengers Triple H and John Cena to retain the championship. The other was a singles match from the ECW brand, in which Kane defeated ECW Champion Chavo Guerrero to win the ECW title. From the six scheduled bouts on the undercard, three received more promotion than the others. In a No Disqualification match, Floyd Mayweather Jr. defeated Big Show. The second match involved wrestlers from all three brands fighting in a Money in the Bank ladder match, which CM Punk won. The other match was a retirement match in which Shawn Michaels defeated Ric Flair, leading to Flair's departure from the WWE and a period of retirement from active wrestling.
