The Archdiocese of Mexico () is a Latin Church ecclesiastical territory or archdiocese of the Catholic Church that is situated in Mexico City, Mexico. It was erected as a diocese on 2 September 1530 and elevated to an archdiocese on 12 February 1546. The archdiocese is one of the largest in the world, with over four million Catholics, surpassed only by Guadalajara, São Paulo and Milan. Prior to 2019, the archdiocese was the largest in the world, with nearly 8 million Catholics. In September 2019, Pope Francis approved the division of the archdiocese, erecting three new  suffragan dioceses from its territory: Azcapotzalco, Iztapalapa, and Xochimilco. These are the only three suffragans within the ecclesiastical province of which the archdiocese is the metropolitan see. Today, the archdiocese’s territory comprises most of Mexico City, with the exception of the three new dioceses, each of which is coextensive with its eponymous borough. The cathedra of the archdiocese is found within the Metropolitan Cathedral in Mexico City. Bishops. Ordinaries. Ordinaries who became Cardinals:
