Arena Naucalpan 23rd Anniversary Show

The Arena Naucalpan 23rd Anniversary Show was a major annual professional wrestling event produced and scripted by the Mexican professional wrestling promotion International Wrestling Revolution Group (IWRG), which took place on December 17, 2000 in Arena Naucalpan, Naucalpan, State of Mexico, Mexico. As the name implies the show celebrated the 23rd Anniversary of the construction of Arena Naucalpan, IWRG's main venue in 1977. The show is IWRG's longest-running show, predating IWRG being founded in 1996 and is the fourth oldest, still held annual show in professional wrestling.

In the main event of the show Último Vampiro ("The Last Vampire") defeated Oficial in a Lucha de Apuestas, mask vs. mask match, forcing Oficial to unmask and state his birth name per lucha libre traditions. In the semi-main event match Los Megas (Mega and Super Mega) successfully defended the IWRG Intercontinental Tag Team Championship against the tag team of Fantasy and Star Boy
