The CMLL World Light Heavyweight Championship (Campeonato Mundial Semi Completo de CMLL in Spanish) is a singles professional wrestling world championship promoted by Consejo Mundial de Lucha Libre (CMLL) since 1991. 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 Light Heavyweight weight class in Mexico is between 92 kg (203 lb) and 97 kg (214 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 rules.
