Arena Naucalpan 22nd Anniversary Show

The Arena Naucalpan 22nd 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 19, 1999 in Arena Naucalpan, Naucalpan, State of Mexico, Mexico. As the name implies the show celebrated the 22nd 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.

The main event of the show featured the "Millennium Cup" finals celebrating the imminent turn of the millennium. In the finals El Hijo del Santo defeated Scorpio Jr. two falls to one to win the Cup. In the semi-main event Super Parka won a 14-man torneo cibernetico match that featured both IWRG regulars and a number of Japanese wrestlers from Toryumon in Japan.
