WrestleMania X8 (also known as WrestleMania 18) was the 18th annual WrestleMania professional wrestling pay-per-view (PPV) event produced by the World Wrestling Federation (WWF). It took place on St Patrick’s Day, March 17, 2002, at the SkyDome in Toronto, Ontario, Canada, the second WrestleMania at that venue after WrestleMania VI in April 1990. The event marked the final WrestleMania event held under the WWF name and the Attitude Era, as the company entered the Ruthless Aggression Era in April and renamed to World Wrestling Entertainment (WWE) a month later. It was also the last WrestleMania held before the introduction of the brand extension just a week after the event. The record-breaking attendance for the SkyDome of 68,237 grossed approximately $6.1 million CAD ($3.9 million USD). WrestleMania weekend also included WWF Fan Axxess at the Canadian National Exhibition's Automotive Building.

Eleven matches were contested at the event. The Rock defeated Hollywood Hulk Hogan in the main attraction dubbed "Icon vs. Icon", while in the final match, Triple H defeated Chris Jericho to win the Undisputed WWF Championship. In other prominent matches on the undercard Stone Cold Steve Austin defeated Scott Hall, The Undertaker defeated Ric Flair in a no disqualification match, and Rob Van Dam defeated William Regal to win the WWF Intercontinental Championship.
