The AAA Mega Championship (often referred to as the AAA World Heavyweight Championship in English and known as the Mega Campeonato AAA in Spanish) is a men's professional wrestling world heavyweight championship promoted by Mexican promotion Lucha Libre AAA Worldwide (AAA). The current champion is El Hijo del Vikingo, who is in his second reign since defeating Alberto El Patrón at Alianzas in Mexico City on May 31, 2025.

The title was revealed in 2007 via a single elimination tournament billed as the Torneo Campeón De Campeones (Champion of Champions Tournament), which effectively unified the IWC World Heavyweight Championship, Grand Prix Championship Wrestling (GPCW) SUPER-X Monster Championship, Mexican National Heavyweight Championship, and UWA World Light Heavyweight Championship. The tournament field included the four reigning champions of the aforementioned titles and the number one contender to each championship. IWC World Heavyweight Champion El Mesías became the first AAA Mega Champion upon defeating UWA World Light Heavyweight Champion Chessman in the final round.
