The CMLL World Middleweight Championship (Campeonato Mundial Peso Medio de CMLL in Spanish) is a professional wrestling world championship promoted by the Mexican Lucha Libre wrestling-based promotion Consejo Mundial de Lucha Libre (CMLL). As it is 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 (181 lb) and 87 kg (192 lb), but is not always strictly enforced. Because Lucha Libre emphasizes the lower weight classes, this division is considered more important than the normally more prestigious heavyweight division of a promotion. All title matches take place under two out of three falls rule
