The Roman Catholic Archdiocese of Adelaide is a Latin Church metropolitan archdiocese of the Catholic Church in Australia located in Adelaide, South Australia. Cathedral St Francis Xavier's Cathedral, Adelaide is the seat of the Catholic Archbishop of Adelaide. History On 5 April 1842 the Apostolic Vicariate of Adelaide was erected, on territory split from the Apostolic Vicariate of New Holland and Van Diemen's Land (the later primatial Archdiocese of Sydney), both missionary pre-diocesan jurisdictions. It was promoted as the Diocese of Adelaide two weeks later on 22 April 1842, just six years after the first fleet arrived to Glenelg. In 1845 it lost territory to establish the Apostolic Vicariate of King George Sounde - The Sound, which it recuperated in 1847 at the vicariate's suppression. On 10 May 1887 it was promoted as the Archdiocese of Adelaide, while losing territory to establish the Roman Catholic Diocese of Port Augusta. It had a papal visit from Pope John Paul II in November 1986. On 19 March 2020, Patrick O'Regan was announced by Pope Francis to be the 12th Archbishop of Adelaide.
