The Aniversario de Arena México show is an annual major professional wrestling show produced by Consejo Mundial de Lucha Libre (CMLL) to commemorate the opening of Arena México, the promotion's main venue, in 1956. The event usually takes place in April with very few exceptions in place of the promotion's regular Friday Night Super Viernes series of shows. Detailed results of a number of older events have not been found and in some cases no results or planned matches have been found documented, leading only to the knowledge that an event probably took place, but no confirmation of date or other details were found. The most recent show was the 63. Aniversario de Arena México show that took place on April 26, 2019. Up until 1991 CMLL operated under the name Empresa Mexicana de Lucha Libre (EMLL) or some times as NWA-EMLL, to promote their association with the National Wrestling Alliance (NWA) that ended in 1991 and prompted the name change.
