Triplemanía XXIX is an upcoming professional wrestling supercard event that will be produced and scripted by the Mexican professional wrestling promotion Lucha Libre AAA Worldwide (AAA or Triple A). The event is scheduled to take place on August 14, 2021 at Arena Ciudad de México in Mexico City. It will mark the 29th year in a row that AAA has held a Triplemanía show, and the 35th overall show held under the Triplemanía banner since 1993. The annual Triplemanía show is AAA's biggest event of the year, serving as the culmination of major storylines in what has been described as AAA's version of WrestleMania or their Super Bowl event. The event will also see the return of live ticketed fans, marking one of the first times AAA allowed this during the COVID-19 pandemic.
