WrestleMania VI was the World Wrestling Federation's (WWF) sixth WrestleMania professional wrestling pay-per-view event and the first to be held outside of the United States. It took place on April 1, 1990, at the SkyDome in Toronto, Ontario, Canada with an announced attendance of 67,678 – then a record for the Skydome.

Aside from its record-breaking attendance, the event is arguably best remembered for "The Ultimate Challenge" – the main event match which saw Hulk Hogan (WWF World Heavyweight Champion) vs. The Ultimate Warrior (WWF Intercontinental Heavyweight Champion), in which both championship titles were on the line. On February 3, 1990, a week after Hogan and Warrior crossed paths in the 1990 Royal Rumble match, Hogan put forth "The Ultimate Challenge" to Warrior, and had to know whether Hulkamania or the power of Warrior was the strongest force in the WWF. On February 10, the match was officially announced as the main event of WrestleMania VI by then WWF President Jack Tunney. On February 24, Tunney announced that both the WWF World Heavyweight Championship and Intercontinental Heavyweight Championship would be on the line for the first-time ever during the match. At WrestleMania VI, Warrior won his sole WWF World Heavyweight Championship.

At WrestleMania VI, Brutus Beefcake was the first person to pin Curt Hennig, a.k.a. Mr. Perfect, in a televised match, thus ending Perfect's lengthy undefeated streak on television. Hennig had actually been beaten on house shows before WrestleMania VI, as the announcers said nothing about his "perfect record" during the match.
