The Mexican National Tag Team Championship (Campeonato Nacional de Parejas) is a national Mexican professional wrestling championship controlled by the Comisión de Box y Lucha Libre Mexico D.F. (Mexico City Boxing and Wrestling Commission) and competed for by two-man tag teams. The championship was created in 1957, promoted regularly until 2003, and intermittently until 2011 when the last known defense took place. Empresa Mexicana de Lucha Libre (EMLL) had control of the championship from its creation until 1992,^{[lower-alpha 2]} at which point it was transferred to AAA.^{[lower-alpha 3]} The championship history up until 1982 is only partially known, with periods of times where it is unclear who held the championship, but it is generally accepted that the lineage began in 1957 when Los Hermanos Shadow (The Shadow Brothers; Blue Demon and Black Shadow) won an eight-team tournament to be crowned champions.^[1] The championship was reintroduced in 2020 after previously being abandoned in 2011.

In the mid-1990s there was confusion about who was recognized as champions for a period of time. In December 1995, one half of then-championship team Los Guerreras, Fuerza Guerrera, left AAA, which led to the promotion declaring the title vacant.^[2] On January 12, 1996, new champions were crowned as Juventud Guerrera and Psicosis defeated Volador and El Mexicano to claim the titles.^[3] When Juventud also left AAA, the Comisión de Box y Lucha Libre decided that Los Guerreras were never officially stripped of the championship, refusing to recognize Juventud Guerrera and Psicosis as champions.^[4] In August 1996, the commission finally declared the championship vacant and returned the championship belts to AAA for future use.^[4]

The last championship team under AAA's control was Octagón and La Parka,^{[lower-alpha 4]} who won the championship on June 20, 2003, when they defeated Electroshock and Chessman. In early 2009, AAA stopped promoting all Mexican National Championships, opting to focus on their AAA branded championships.^[6] Octagón and La Parka were never stripped of the championship, but did not defend them on any AAA shows after late 2007. From that point on the championship was only defended twice on the Mexican independent circuit, in March 2009,^[7] and then in December 2011.^{[lower-alpha 5]} The championship was inactive after the last known defense.^{[lower-alpha 5]} until February 19, 2020 when Consejo Mundial de Lucha Libre (CMLL; formerly EMLL) announced that they were bringing the championship back.^[9]

Los Depredadores (Magnus and Rugido) are the current champions. They defeated Esfinge and Fugaz on July 9, 2023. There have been at least 44 championship reigns since 1957. Los Destructores (Tony Arce and Vulcano) held the championship three times,^[10][11][12] the most of all recognized champions, while Tony Arce holds the individual record with four reigns.^[13] Los Metálicos (Oro and Plata) had the shortest verified reign, six days in December 1991.^[14] Octagón and La Parka's reign lasted 3,110 days, the longest known reign of any champions.^[15] As with all professional wrestling championships, matches for the Mexican National Tag Team Championship were not won or lost competitively, but by a pre-planned ending to a match, with the outcome determined by the CMLL bookers and match makers.^{[lower-alpha 6]} On occasion a promotion declared the championship vacant, which meant there was no champion at that point in time. This was either due to a storyline,^{[lower-alpha 7]} or real life issues such as a champion suffering an injury being unable to defend the championship,^{[lower-alpha 8]} or leaving the company.^{[lower-alpha 9]} All title matches took place under two out of three falls rules.^{[lower-alpha 10]}
