AAA Mega Championship

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". 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.

Reigns
Overall, there have been 20 AAA Mega Championship reigns and 13 total champions, and the title has been vacated twice. The inaugural champion was El Mesías, who defeated Chessman in the final of an eight-man tournament at the Verano de Escándalo event on September 16, 2007, to become champion. El Texano Jr.'s first reign as champion gave the title world status when he defended it in Mexico. El Hijo del Vikingo had the longest reign at 833 days. Jeff Jarrett had the shortest reign at 83 days. El Mesías holds the record for the most reigns with four. El Texano Jr., Fénix, Kenny Omega, and El Hijo Del Vikingo are the only four wrestlers to have held the title for a full consecutive year.

In 2011, the then-AAA Mega Champion and Total Nonstop Action Wrestling (TNA) founder Jeff Jarrett appeared with a redesigned version of the title belt on TNA programming. TNA used the Mega Championship belt on their programming, but due to Spike TV, then TNA's broadcaster, not allowing TNA to refer to AAA by name, a silver hexagonal plate was used to cover the AAA faceplate. While Jarrett appeared in TNA, the title was referred to as the "Mexican Heavyweight Championship". On April 21, 2013, the title was defended outside AAA for the first time at Puerto Rico's World Wrestling League (WWL). In March 2015, the AAA Mega Champion El Patrón Alberto defended the championship in Lucha Underground, made possible through AAA's joint ownership of Lucha Underground.

Nic Nemeth is the current champion in his first reign. He defeated Alberto El Patrón for the vacant title at Triplemanía XXXII: Monterrey on April 27, 2024 in Monterrey, Mexico. The previous champion, El Hijo Del Vikingo, vacated the title due to injury.
