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, an American professional wrestling promotion based in Connecticut. 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. It contributes to the worldwide commercial success of WWE through media, merchandise, and shows. 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.
WrestleMania's widespread success helped transform the professional wrestling sport. The event has facilitated the rise to stardom of several top WWE wrestlers. Celebrities such as Aretha Franklin, Cyndi Lauper, Muhammad Ali, Mr. T, Alice Cooper, Lawrence Taylor, Pamela Anderson, Mike Tyson, Donald Trump, Floyd Mayweather, Pete Rose, Burt Reynolds, Mickey Rourke, Snoop Dogg, Sean "Diddy" Combs, Kid Rock, Fred Durst, Ozzy Osbourne, Ronda Rousey, Kid Ink and Shaq have participated or made special appearances within the events.

WrestleMania III in the Detroit suburb of Pontiac, Michigan was the highest-attended indoor sports event in the world, with 93,173 fans in attendance. The record stood until February 14, 2010, when the 2010 NBA All-Star Game broke the indoor sporting event record with an attendance of 108,713 at Cowboys Stadium.
