WrestleMania is a professional wrestling event held annually between mid-March and mid-April by the American company WWE, the world's largest professional wrestling promotion. Since premiering in 1985, 41 events have been held, with its most recent 41st edition occurring at Allegiant Stadium in Paradise, Nevada, on April 19 and 20, 2025. WrestleMania was WWE's first pay-per-view (PPV) produced and is the most successful annual professional wrestling event in history. The event has been broadcast through traditional PPV since 1985 and has been available via livestreaming since WrestleMania XXX in 2014, which was WWE's first major event available through this medium. WrestleMania was conceptualized by former WWE executive chairman Vince McMahon and named by ring announcer and WWE Hall of Famer Howard Finkel. It is the company's flagship event and along with Royal Rumble, SummerSlam, Survivor Series, and Money in the Bank, it is referred to as one of the "Big Five", WWE's five biggest annual events of the year.
