The CMLL World Middleweight Championship is a professional wrestling championship promoted by the Mexican Lucha Libre wrestling-based promotion Consejo Mundial de Lucha Libre (CMLL). 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 middleweight weight class in Mexico is between 82 kg (180 lb) and 87 kg (190 lb), but is not always strictly enforced.
