The Metropolitan Archdiocese of Buenos Aires (Archidioecesis Metropolitae Bonaerensis) is a Latin Church ecclesiastical territory or archdiocese of the Catholic Church in Argentina. It is a metropolitan archdiocese with 13 suffragan sees in the country, including two Eastern Catholic eparchies.

The Metropolitan Archbishopric of Buenos Aires was the Primatial see (protocollary first-rank) of Argentina,^[1][2][3] although the incumbent Metropolitan may be outranked by Cardinals or more senior ones. On 13 March 2013, Cardinal Archbishop Jorge Mario Bergoglio was elected pope, taking the name of Francis. On 22 July 2024, the primatial see of Argentina was transferred to the Archdiocese of Santiago del Estero .^[4] The current archbishop, since 26 May 2023, is Jorge Ignacio García Cuerva.

At the beginning of the twentieth century, Buenos Aires was the second largest Catholic city in the world after Paris.^[5][6] In 2014 the Archdiocese pastorally served 2,721,000 Catholics (91.6% of 2,971,000 total) in an area of 205 km² in 186 parishes and 183 missions with 783 priests (456 diocesan, 327 religious), 11 deacons, 1,915 lay religious (477 brothers, 1,438 sisters) and 53 seminarians. It is divided into the four zonal vicaries—Flores, Devoto, Belgrano and Centro—which are further subdivided into 20 deaconates.
