The Roman Catholic Church in East Africa's major Indian Ocean island state Madagascar comprises only a Latin hierarchy, which is composed of five ecclesiastical provinces, whose Metropolitan Archbisdhoprics have a total of seventeen suffragan dioceses.
There is no Eastern Catholic, pre-diocesan or other exempt jurisdiction.
There is also an Apostolic Nunciature to Madagascar as papal diplomatic representation (embassy-level), in national capital Antananarivo.
There are no titular sees.
All defunct jurisdictions have current successor sees.
