WrestleMania X-Seven was the seventeenth annual WrestleMania professional wrestling pay-per-view produced by the World Wrestling Federation. It took place on April 1, 2001 at the Reliant Astrodome in Houston, Texas. The event is the highest grossing in the company's history and the highest grossing professional wrestling pay-per-view ever. A record-breaking attendance for the Reliant Astrodome of 67,925 resulted in gross receipts of $3.5 million USD.

• The second time that the main event featured The Rock and "Stone Cold" Steve Austin (They met each other previously at WrestleMania XV. A third match between the two would happen again at WrestleMania XIX.)
• This event holds the record for most title changes at a single WrestleMania with 5 title changes. The WWE Championship, Tag Team Championship, Women's Championship, European Championship and Hardcore Championship titles all changed hands at this event.
• Featured an appearance by Motörhead who would play Triple H's theme music as he walked down the ramp to the ring. Motörhead would appear again at WrestleMania 21 to perform Triple H's theme music yet again.
• This WrestleMania would take place only about a week after the World Wrestling Federation announced the purchase of long time rival promotion WCW.
• This was the first WrestleMania whose title included a combination of a Roman numeral and a number being spelled out (rather than using purely Roman or Arabic numerals).
• This was the first WrestleMania logo to make use of the font Bodega Sans.
• Bobby "The Brain" Heenan called his first WrestleMania Match in 8 years alongside "Mean" Gene Okerlund.
