The Mexican National Cruiserweight Championship (Campeonato Nacional Crucero in Spanish) is a national Mexican singles professional wrestling championship controlled by Comisión de Box y Lucha Libre Mexico D.F. (Mexico City Boxing and Wrestling Commission). From its creation in 1983 it was not promoted by one specific promotion but shared between many Mexican promotions primarily, but not exclusively Empresa Mexicana de Lucha Libre (EMLL). In the mid-1990s Asistencia Asesoría y Administración (AAA) gained primary booking control of the championship. Being a professional wrestling championship, it is not won legitimately: it is instead won via a scripted ending to a match or awarded to a wrestler because of a storyline. The official definition of the Cruiserweight class in Mexico is between 97 kg (214 lb) and 107 kg (236 lb),, but is not always strictly enforced.
Ángel Blanco became the first National Cruiserweight Champion when he won the inargual tournament on November 13, 1984 defeating Insolito in the final match. In the mid-1990s AAA gained control of the championship when then champion Blue Demon, Jr. began working for AAA full-time. When Blue Demon, Jr. lost the Cruiserweight Championship to Karis La Momia AAA took full control all aspects of the Championship. In 1996 Karis la Momia changed his ring character to La Parka and had to vacate the title since his past history working as Karis was not publicly acknowledged by AAA. In 1999 La Parka regained the title, becoming the only two time champion. The title was barely defended since between the early 2000s and when it was officially vacated by AAA on December 8, 2008.
