Undefeated WrestleMania streak of The Undertaker

The Streak was a series of 21 straight victories for professional wrestler The Undertaker (Mark Calaway) at WWE's premier annual event, WrestleMania. It began at WrestleMania VII in 1991 when he beat Jimmy Snuka, with the final win coming against CM Punk at WrestleMania 29 in 2013; The Undertaker was absent from WrestleMania X (1994) and WrestleMania 2000, owing to injury. Overall, he defeated 18 men during The Streak, which included three bouts with Triple H and two each opposite Kane and Shawn Michaels, as well as a handicap match against A-Train and Big Show at WrestleMania XIX. Although part of professional wrestling storyline, this run of victories was described by sports news publication The 42 as the "greatest winning streak in sport", while Sky Sports likened it to that of boxer Floyd Mayweather.

The Streak became the cornerstone of WrestleMania, with a potential win over The Undertaker at the event being described as a greater honor than winning the WWE Championship. At WrestleMania XXX in 2014, The Undertaker lost to Brock Lesnar. For years, debate had revolved around who, if anybody, should break The Streak, with prominent wrestlers giving comment.
