The Catholic Church in the Gambia and Sierra Leone, two Anglophone (ex-British) West African countries, is composed solely of a Latin hierarchy, comprising:
There are no Eastern Catholic or pre-diocesan jurisdictions or overlapping ordinariates.
Neither country has a national Episcopal Conference, but they form a joint one for the Gambia and Sierra Leone, which hosts it in Freetown. [1]
There are no titular sees. All defunct jurisdictions are precursors of present sees.
There formally is an Apostolic Nunciature (embassy-level papal diplomatic representation) to Sierra Leone and an Apostolic Nunciature to The Gambia, but both are vested in the Apostolic Nunciature to Liberia (in its capital Monrovia).
