The IWRG 7th Anniversary Show was a major lucha libre event produced and scripted by the Mexican International Wrestling Revolution Group (IWRG) professional wrestling promotion on January 1, 2003. The show was held in Arena Naucalpan, Naucalpan, State of Mexico, which is IWRG's primary venue. As the name indicates the event commemorates the anniversary of IWRG, which was founded on January 1, 1996.

Due to incomplete records for many Mexican wrestling promotions in the 20th and early parts of the 21st century, only one match result has been verified. Magazines mentioned the main event match between Último Vampiro and Bombero Infernal, stating the date and the event it was held at. In the main event Último Vampiro defeated Bombero Infernal in a Lucha de Apuestas, or "bet match", forcing Bombero Infernal to have all his hair shaved off as a result. Due to incomplete record keeping, no other match results have been verified.

Wrestler-turned-promoter Adolfo "Pirata" Moreno began promoting wrestling shows in his native Naucalpan de Juárez, Mexico, bringing in wrestlers from Empresa Mexicana de Lucha Libre (EMLL) to Naucalpan as well as featuring wrestlers from the Mexican independent circuit. Later on he would promote shows mainly in "Arena KO Al Gusto" and served as the Universal Wrestling Association (UWA) partner, using the name Promociones Moreno as the business name for his promotional efforts. In 1977 Moreno bought the run down Arena KO Al Gusto and had Arena Naucalpan built in its place, an arena designed specifically for wrestling shows, with a maximum capacity of 2,400 spectators for the shows. Arena Naucalpan became the permanent home for Promociones Moreno, with very few shows held elsewhere.
