The Roman Catholic Church in Angola is composed of a Latin hierarchy only, which comprises three ecclesiastical provinces, each headed by a Metropolitan Archbishop, and a total of fifteen suffragan dioceses.
Although exempt (i.e. immediately subject to the Holy See), the Diocese of São Tomé and Príncipe, an Atlantic island country which shares a Portuguese colonial history (and linguistic legacy) with Angola, is part of the transnational Episcopal Conference of Angola and São Tomé, while neither has a national Episcopal Conference.
Neither country has an Eastern Catholic or pre-diocesan jurisdiction.
There is an Apostolic Nunciature to Angola (in national capital Luanda) as papal diplomatic representation (embassy-level), into which is also vested the Apostolic Nunciature to São Tomé and Príncipe.
Excluding precursors of present sees (usually pre-diocesan).
