The Mexican National Cruiserweight Championship is a national Mexican singles professional wrestling championship controlled by Comisión de Box y Lucha Libre Mexico D.F.. From its establishment in 1983, no one promotion promoted the championship but was shared between several Mexican promotions, and not exclusively by Empresa Mexicana de Lucha Libre (EMLL). In the mid-1990s AAA gained primary booking control of the championship. Being a professional wrestling championship, it was not won legitimately but via a scripted ending to a match or awarded to a wrestler because of a storyline. The official definition of the cruiserweight weightclass in Mexico is between 77 kg (170 lb) and 80 kg (180 lb).
