Guerra del Golfo (Spanish for "Gulf War") is both the name of a major show series promoted by the Mexican Lucha Libre, or professional wrestling promotion International Wrestling Revolution Group (IWRG) as well as the name of the tournament match that is the focal point of the show. The tournament consists of two first-round steel cage matches where the last person in the cage advances to the final match of the night. In the finals the two losers face off in a cage match where the loser of that match is either unmasked or forced to have their hair shaved off under Luchas de Apuestas rules. There have been a total of 10 shows since the first show in 2005. So far three wrestlers have lost their masks and seven have been shaved bald.
Starting as far back as at least 2000, the Mexican wrestling promotion International Wrestling Revolution Group (IWRG; Sometimes referred to as Grupo Internacional Revolución in Spanish) has held several annual events where the main event was a multi-man steel cage match where the last wrestler left in the cage would be forced to either remove their wrestling mask or have their hair shaved off under Luchas de Apuestas, or "bet match", rules. From 2005 IWRG has promoted a spring time show promoting the steel cage match concept under the name Guerra del Golfo, or "Gulf War", referring to the Gulf of Mexico, not the Gulf War in the middle east. The Gurerra del Golfo shows always featured two "qualifying" steel cage matches where the loser would later be forced to face off against each other in the main event of the show, a final cage match where the loser would be forced to either unmask or have his/her hair shaved off. The use of the steel cage in three matches distinguishes the Guerra del Golfo event from other Steel cage matches held throughout the year such as the IWRG El Castillo del Terror ("The Tower of Terror"), IWRG Guerra de Sexos ("War of the Sexes") or IWRG Prison Fatal ("Deadly Prison") shows. The Guerra del Golfo shows, as well as the majority of the IWRG shows in general, are held in "Arena Naucalpan", owned by the promoters of IWRG and their main arena. Starting in 2008 IWRG has held at least one Guerra del Golfo match each year, with the 2015 edition being the tenth over all show.
