WrestleMania 33 was the thirty-third annual WrestleMania professional wrestling pay-per-view (PPV) event and WWE Network event produced by WWE. It took place on April 2, 2017, at Camping World Stadium in Orlando, Florida. WrestleMania 33 was a joint-promotion event for the Raw and SmackDown brands, the first since WrestleMania XXVII in 2011 as the brand split ended that year, but was reintroduced in July 2016.
Thirteen matches were contested at the event, including three on the pre-show. For the first time since WrestleMania 29 in 2013, two world championships were contested: Raw's Universal Championship and SmackDown's WWE Championship; it marked the first time that the Universal Championship, SmackDown Women's Championship, and new Cruiserweight Championship were defended at WrestleMania. In the main event, Roman Reigns defeated The Undertaker in a No Holds Barred match, giving Undertaker his second loss at WrestleMania. In addition, Brock Lesnar defeated Goldberg to become the Universal Champion, thus becoming the first wrestler to win both the WWE Championship and Universal Championship, and Randy Orton defeated Bray Wyatt to win his ninth WWE Championship. The event also marked the surprise return of The Hardy Boyz, who won the Raw Tag Team Championship. It was also the first WrestleMania to be on the air past midnight Eastern time.
WWE claimed an attendance of 75,245 for WrestleMania 33. This number has been disputed, as The A.V. Club wrote that it was "almost certainly a fake number" as WWE "has had a reputation for wildly inflating the attendance figure—as Vince McMahon once said on an investor's call, the fake number is for entertainment purposes", while wrestling journalist Dave Meltzer described it as "a total worked number even more than usual".
