The Mexican National Heavyweight Championship is a Mexican Lucha Libre championship created and sanctioned by the Mexico City Boxing and Wrestling Commission. While the Commission sanctions the title, it does not promote the events in which the Championship is defended. From 1933 until the mid-1990s, Consejo Mundial de Lucha Libre (CMLL) controlled the Championship, since then AAA gained control of the championship, after the Commission granted them control of the championship. In 2006 the championship was abandoned and replaced by the AAA Mega Championship. In 2009 the championship became active again on the Mexican Independent circuit until 2013. CMLL brought the championship back in 2017. Since the championship is designated as a heavyweight title, the championship can only officially be competed for by wrestlers weighing at least 105 kg (231 lb). However, the regulation is not strictly adhered to.

Consejo Mundial de Lucha Libre Co., Ltd. is a lucha libre professional wrestling promotion based in Mexico City. The promotion was previously known as Empresa Mexicana de Lucha Libre (EMLL). Founded in 1933, it is the oldest professional wrestling promotion still in existence.
