The Mexican National Trios Championship ("Campeonato National Trios" in Spanish) is a three-man tag team professional wrestling championship, sanctioned by the "Comisión de Box y Lucha Libre Mexico D.F." ("Mexico City Boxing and Wrestling Commission"), which oversees all matches where the championship is defended. Since its creation in 1985 the championship has been promoted by several major Mexican wrestling promotions, Empresa Mexicana de Lucha Libre (EMLL), Asistencia Asesoría y Administración (AAA) and is currently promoted by Consejo Mundial de Lucha Libre (CMLL, formerly EMLL). The change from promotion to promotion was approved by the commission if the trios champions left one promotion to work for the other. As it is a professional wrestling championship, it is not won or lost competitively, but instead by the decision of the bookers of a wrestling promotion. The title is awarded to a team after the team "wins" a match to maintain the illusion that professional wrestling is a competitive sport. All title matches take place under two-out-of-three falls rules.
