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 "Millenium 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.

The location at Calle Jardín 19, Naucalpan Centro, 53000 Naucalpan de Juárez, México, Mexico was originally an indoor roller rink for the locals in the late part of the 1950s known as "Cafe Algusto". By the early-1960s, the building was sold and turned into "Arena KO Al Gusto" and became a local lucha libre or professional wrestling arena, with a ring permanently set up in the center of the building. Promoter Adolfo Moreno began holding shows on a regular basis from the late 1960s, working with various Mexican promotions such as Empresa Mexicana de Lucha Libre (EMLL) to bring lucha libre to Naucalpan. By the mid-1970s the existing building was so run down that it was no longer suitable for hosting any events. Moreno bought the old build and had it demolished, building Arena Naucalpan on the same location, becoming the permanent home of Promociones Moreno. Arena Naucalpan opened its doors for the first lucha libre show on December 17, 1977. From that point on the arena hosted regular weekly shows for Promociones Moreno and also hosted EMLL and later Universal Wrestling Association (UWA) on a regular basis. In the 1990s the UWA folded and Promociones Moreno worked primarily with EMLL, now rebranded as Consejo Mundial de Lucha Libre (CMLL).
