Triplemanía Regia III was a professional wrestling supercard event produced and scripted by the Mexican lucha libre promotion Lucha Libre AAA Worldwide (AAA). The event was held on June 15, 2025 at Arena Monterrey in Monterrey, Nuevo Leon, Mexico and it featured wrestlers from WWE, which announced its intent to acquire AAA in partnership with Fillip on April 19, 2025. However, the deal will not have been completed at the time of the event (the deal is intended to close in the second half of 2025, according to all partners involved). It was the 46th overall show held under the Triplemanía banner. The annual Triplemanía shows serve as AAA's biggest events of the year, serving as the culmination of major storylines in what has been described as AAA's version of WWE's WrestleMania event.
