The CMLL World Heavyweight Championship (Campeonato Mundial Completo de CMLL in Spanish) is a singles professional wrestling championship promoted by Consejo Mundial de Lucha Libre (CMLL). The Championship has been in existence since 1991. Unlike other heavyweight titles such as the WWE Championship or the IWGP Heavyweight Championship, it is not the main championship in the promotion because CMLL has emphasized the lower weight levels since there are more workers in the lower levels. The title was the first to be created after Empresa Mexicana de la Lucha Libre changed its name to Consejo Mundial de Lucha Libre in the early 1990s.
