The CMLL 80th Anniversary Show was a professional wrestling event produced by Consejo Mundial de Lucha Libre (CMLL) that took place on September 13, 2013, in CMLL's home arena Arena México in Mexico City, Mexico. The event commemorated the 80th anniversary of CMLL, the oldest professional wrestling promotion in the world. CMLL's anniversary show is their biggest, most important show of the year, comparable to the Super Bowl for the National Football League or WrestleMania for WWE.

For the show CMLL decided to combine two of their biggest, longest running storyline feuds as they booked a Relevos Suicidas (Spanish for "Suicide Relay") match for the show. In a Relevos Suicidas two tag teams wrestle each other and as a result of the match one team is then forced to fight against each other under Lucha de Apuestas, or "Bet match", rules. Traditionally the losing team would be forced to wrestle for their masks as a "punishment" for losing the match, but for this show CMLL changed it so that the winning team would win the right to fight for their masks, playing off the fact that the two teams actually wanted to fight their partner in a Lucha de Apuesta match. Volador Jr. and La Sombra made up one team, former friends turned bitter rivals who were in the middle of a several-year long feud. On the other side was Atlantis and Último Guerrero, again former partners and friends who were also involved in a multiple-year spanning feud.
