WrestleMania XV was the 15th annual WrestleMania professional wrestling pay-per-view (PPV) event produced by the World Wrestling Federation (WWF, now WWE). It took place on March 28, 1999, at the First Union Center in Philadelphia, Pennsylvania. Ten professional wrestling matches were scheduled on the event's card. The ticket sales of 20,276 drew a gross of $1,437,050.

The main event saw the challenger Stone Cold Steve Austin face The Rock in a no disqualification match for the WWF Championship. The penultimate match saw The Undertaker wrestle Big Boss Man in a Hell in a Cell match. Lower on the card, six of the promotion's seven active championships were defended, including the first WrestleMania defense of the Hardcore Championship. Also on the undercard was a Brawl for All match, an unscripted type of shootfight between wrestler Bart Gunn and boxer/mixed martial artist Butterbean. This event also marked the final WWF appearance for Gorilla Monsoon, who died in October that year.
