WrestleMania is a professional wrestling event produced annually between mid-March to early April by WWE, an American professional wrestling promotion based in Stamford, Connecticut. WWE first produced the event in 1985 and has since produced 33 editions, with the most recent having been held in Orlando, Florida on April 2, 2017 and thirty-fourth to be held in New Orleans, Louisiana on April 8, 2018. WrestleMania, WWE's flagship event, airs on pay-per-view (PPV) and WWE Network and 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 professional wrestling. The event has facilitated the rise to stardom of several top WWE wrestlers.

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, since renamed AT&T Stadium, in Arlington, Texas.
