The 2005 Guerra del Golfo (Spanish for "Gulf War") was the first instance of the recurring IWRG Guerra del Golfo major event produced and scripted by the Mexican professional wrestling promotion International Wrestling Revolution Group ("IWRG"; sometimes referred to as Grupo Internacional Revolución in Mexico). The show, held on December 22, 2005 also commemorated the 28th Anniversary of Arena Naucalpan, IWRG's main venue. In this instance the "Gulf" referred to in the title is the Gulf of Mexico, not the Gulf War in the Persian Gulf.
