The Apostolic Prefecture of Falkland Islands (Latin: Apostolica Præfectura de Insulis Falkland) is a Latin Church missionary ecclesiastical jurisdiction or apostolic prefecture of the Catholic Church covering the Falkland Islands and South Georgia and the South Sandwich Islands,[1][2][3] UK Southern Atlantic Ocean overseas possessions.

The Latin missionary jurisdiction was established on 1 October 1952 as Apostolic Prefecture, splitting the offshore territory of Falkland Islands, South Georgia and the South Sandwich Islands from the Diocese of Punta Arenas in Chile.

An exempt mission sui juris, it was created on 18 August 1986 for the British overseas territory of Saint Helena, Ascension and Tristan da Cunha, comprising the Atlantic Ocean islands of Saint Helena, Ascension Island and Tristan da Cunha, splitting these territories from the Archdiocese of Cape Town.

It comprises a church or chapel on each island: From the start, the office of its ecclesiastical superior has been vested in the Apostolic Prefect of the Falklands, another UK Southern Atlantic overseas possession.

So far, all incumbents have been members of Roman rite missionary congregations, none titular bishops
