EMLL 58th Anniversary Show

The EMLL 58th Anniversary Show (Spanish: 58. Aniversario de CMLL) was a professional wrestling major show event produced by Empresa Mexicana de Lucha Libre (EMLL) that took place on September 8, 1991, in Arena Mexico, Mexico City, Mexico. This would be the last show promoted under the EMLL name as the organization changed its name to Consejo Mundial de Lucha Libre in the winter of 1991. The event commemorated the 58th anniversary of EMLL, the oldest professional wrestling promotion in the world. The Anniversary show is EMLL's biggest show of the year, their Super Bowl event. The CMLL Anniversary Show series is the longest-running annual professional wrestling show, starting in 1934.

The show consisted of four matches, with the main event being a Lucha de Apuestas, hair vs. hair match between Konnan, Cien Caras, and Perro Aguayo. The show also featured a Six-man tag team match, an eight-man match, and a match where Máscara Sagrada defended the Mexican National Light Heavyweight Championship against Pirata Morgan.
