CMLL World Middleweight Championship

The CMLL World Middleweight Championship (Campeonato Mundial peso Medio de CMLL in Spanish) is a professional wrestling world championship promoted by the Mexican wrestling promotion Consejo Mundial de Lucha Libre (CMLL). While weight classes are regularly ignored in wrestling promotions in the United States, with most emphasis placed on "heavyweights", more emphasis is placed on weight classes in Mexican companies who still maintain many weight classes. The official definition of a Middleweight in Mexico is a person under 87 kg (190 lb), but is not strictly adhered to these days.

Because the championship is a professional wrestling championship, it is not won or lost competitively but instead by the decision of the bookers of a wrestling promotion. The title is awarded after the chosen champion "wins" a match to maintain the illusion that professional wrestling is a competitive sport.
