The Apostolic Vicariate of Anatolia (Latin: Vicariatus Apostolicus Anatoliensis) is a Roman Catholic Latin apostolic vicariate in the eastern half of Anatolia (Asian Turkey). The missionary pre-diocesan jurisdiction is not part of any ecclesiastical province. It is under the direction of the Congregation for the Oriental Churches, an unusual structure for a Latin see, and directly dependent on the Holy See. Its cathedral seat is the Marian Cathedral of the Annunciation in İskenderun (Alexandria). It has the Co-Cathedral of St. Anthony of Padua in Mersin as well.
