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.
