The Roman Catholic Archdiocese of Adelaide is a Latin Church metropolitan archdiocese of the Catholic Church in Australia located in Adelaide, South Australia.

St Francis Xavier's Cathedral, Adelaide is the seat of the Catholic Archbishop of Adelaide.

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.

The Roman Catholic Ecclesiastical Province of Adelaide comprises the metropolitan's own archdiocese and these suffragan dioceses:

• Roman Catholic Diocese of Darwin
• Roman Catholic Diocese of Port Pirie

Father Albert Davis (died 2007), a member of the Dominican Fathers, was charged in 2006 with 17 incidents of indecent assault involving seven boys at Blackfriars Priory School from 1956 to 1960. Davis was committed to stand trial in the Adelaide District Court, but he died before proceedings were commenced.

Father Charles Barnett pleaded guilty in 2009 (after extradition from Indonesia) to three child sex charges for events from 1977 to 1985 at Crystal Brook and Port Pirie.

In September 2011, Senator Nick Xenophon used parliamentary privilege to name an Adelaide priest as the alleged perpetrator of sexual assaults on John Hepworth about 50 years earlier. Senator Xenophon alleged that the Vicar-General of Adelaide, Monsignor David Cappo, had been provided with detailed allegations in 2008 but had failed to act upon them, the investigations still being "at a preliminary stage" and the priest concerned not being stood down during the investigation. An independent inquiry by Michael Abbott QC reported that there was no substance to the allegations, although Hepworth had declined to be interviewed for the inquiry.
