The Archdiocese of Anchorage–Juneau (Latin: Archidiœcesis Ancoragiensis–Junellensis) is an ecclesiastical territory of the Roman Catholic Church that covers the entire state of Alaska. The archdiocese is led by an archbishop who serves as pastor of both Our Lady of Guadalupe Cathedral in Anchorage and the Cathedral of the Nativity of the Blessed Virgin Mary in Juneau. The archdiocese is a metropolitan see, with a single suffragan diocese, the Diocese of Fairbanks. The archdiocese was erected in 2020 when Pope Francis merged the former Archdiocese of Anchorage with the former Diocese of Juneau.
