The AAA Mega Championship is a professional wrestling world heavyweight championship in the Mexican Lucha Libre AAA Worldwide (AAA) promotion. Known officially in Spanish as the Mega Campeonato AAA, it is sometimes referred to in the English-language press as the "AAA World Heavyweight Championship".^[5] The title is the top championship of the AAA promotion. The current champion is Nic Nemeth, who is in his first reign. He defeated Alberto El Patrón at Triplemanía XXXII: Monterrey on April 27, 2024 in Monterrey, Mexico.

The title was established in 2007 via a single elimination tournament billed as the "Torneo Campeón de Campeones", or Champion of Champions Tournament, which effectively unified the International Wrestling Council (IWC) World Heavyweight Championship, the Grand Prix Championship Wrestling (GPCW) SUPER-X Monster Championship, the Mexican National Heavyweight Championship, and the Universal Wrestling Association (UWA) World Light Heavyweight Championship. The tournament field included the four reigning champions of the aforementioned titles as well as the number one contender to each championship. El Mesías, who entered the tournament as the IWC World Heavyweight Champion, became the inaugural AAA Mega Champion upon defeating the UWA World Light Heavyweight Champion entrant Chessman in the final round.^[6]
