The CMLL Arena Coliseo Tag Team Championship, is a secondary, much less defended tag team championship promoted by CMLL. As the name indicates it is defended in Arena Coliseo in Mexico City, although there have been a couple of defenses in Arena Mexico. Stuka Jr. and Fuego (shown to the left) were the longest running champions, holding them for over four years. The Coliseo Tag Team title dates back to the 1960s but was abandoned in the 1980s before being brought back in 2000. The belts holds the unofficial distinction of being the ugliest CMLL title belts currently in use.
