List of Catholic dioceses in South Pacific Conference states

The Catholic Church in the South Sea (Oceania, excluding the national episcopal conferences of Australia, of New Zealand, each with dependencies, and of Papua New Guinea and the Solomon Islands) consists only of a variety of Latin jurisdictions, usually covering a whole island state (whether nation or overseas territory of a foreign power) or even more than one, none of which has a large enough episcopate to warrant a national episcopal conference, so they jointly form the Latin "Episcopal Conference of the [South] Pacific", headquartered in Suva (on Fiji). It comprises only:


 * five transnational ecclesiastical provinces, each headed by a Metropolitan Archbishopric, with a total of eleven suffragans: eight bishoprics and -exceptionally, as those are generally exempt- three pre-diocesan (an apostolic prefecture and two independent missions)
 * one exempt diocese, directly subject to the Holy See, on Tonga.

There are no proper Eastern Catholic jurisdictions or quasi-diocesan Ordinariates, but the Byzantine Rite Ukrainian Catholic Church faithful are served by the Ukrainian Catholic Eparchy of Saints Peter and Paul of Melbourne, in and for all Australia, also covering New Zealand and further Oceania.

There are no individual papal diplomatic representations to several British, French, Australian, New Zealand and US overseas possessions (strictly speaking diplomatically covered by the home countries), but the Apostolic Delegation to the Pacific Ocean, headquartered externally in Wellington, New Zealand, covers American Samoa, French Polynesia, Guam (US), New Caledonia (France), Niue (New Zealand), Norfolk Island (Australia, pastorally under its Sydney Archdiocese), Northern Mariana Islands (US), Pitcairn Islands (UK), Tokelau (NZ), the U.S. Minor Outlying Islands (pastorally served by the Archdiocese for the Military Services of the United States) and Wallis and Futuna (France). It also deals with independent Tuvalu. There is formally an Apostolic Nunciature as papal diplomatic representation (embassy level) to Fiji, but it is vested in the Apostolic Nunciature to New Zealand, in its capital Wellington.

There is formally an Apostolic Nunciature to Cook Islands, but it is vested in the Apostolic Nunciature to associated mother country New Zealand in its capital Wellington.
