WrestleMania, (also known informally as Mania and frequently abbreviated to WM) is a professional wrestling pay-per-view event, produced annually between mid-March to early April by WWE, a professional wrestling event produced by the WWE, a Connecticut–based promotion, and broadcast live and available through pay-per-view and the WWE Network. WWE first produced the event in 1985 and has since produced 32 editions, with the thirty-third to be held in Orlando, Florida on April 2, 2017. WrestleMania, WWE's flagship event, is the most successful and longest-running professional wrestling event in history.

WrestleMania was conceptualized by WWE owner Vince McMahon and long time WWE ring announcer and Hall of Famer Howard Finkel is credited with devising the name "WrestleMania" in 1984.
