Triplemanía XX was a professional wrestling event scripted and produced by the AAA promotion, which took place on August 5, 2012, at Arena Ciudad de México in Mexico City, Mexico. The event was the twentieth annual Triplemanía, which is AAA's biggest show of the year, and marked AAA's debut in the new Arena Ciudad de México. The event was headlined by a match between Dr. Wagner Jr. and Máscara Año 2000 Jr., where the loser was forced to unmask himself. In the semi-main event, El Mesías defended the AAA Mega Championship against the 2012 Rey de Reyes, El Hijo del Perro Aguayo. The event also featured Total Nonstop Action Wrestling (TNA) performer Kurt Angle's AAA debut and an induction into the AAA Hall of Fame. This event marked the first time in four years that a Triplemanía was not broadcast live on pay-per-view. Instead, the event would be broadcast in three parts on AAA's official website, starting August 19. The event was attended by 21,000 people, the largest crowd for a professional wrestling event in Mexico in almost five years.

After making a deal with the Televisa television network AAA held their first show in April 1992. The following year Peña and AAA held their first Triplemanía event, building it into an annual event that would become AAA's Super Bowl event, similar to the WWE's WrestleMania being the biggest show of the year. The 2012 Triplemanía was the 20th year in a row AAA held a Triplemanía show and the 25th overall show under the Triplemanía banner. Storylines The Triplemanía XX show featured seven professional wrestling matches with different wrestlers involved in pre-existing scripted feuds, plots and storylines. Wrestlers were portrayed as either heels (referred to as rudos in Mexico, those that portray the "bad guys") or faces (técnicos in Mexico, the "good guy" characters) as they followed a series of tension-building events, which culminated in
