List of Catholic dioceses in Indian Ocean Episcopal Conference

The Roman Catholic Church in the lesser East African Indian Ocean states (not Madagascar) is composed of only a Latin hierarchy, without a proper ecclesiastical province but joined in a single episcopal conference,
comprising five exempt jurisdictions, i.e. directly dependent on the Holy See :

• three exempt dioceses (on Mauritius, Réunion and the Seychelles)
• two missionary pre-diocesan Apostolic vicariates (entitled to titular bishops) : one for the Comoros and Mayotte; the other in above Mauritius.

There are no titular sees.

All defunct jurisdictions have current successors.

There are also three papal diplomatic representations (in fact all vested in the apostolic nunciature (embassy) on Madagascar) :

• the Apostolic Nunciature to Mauritius
• the Apostolic Nunciature to Seychelles
• the Apostolic Delegation to Comoros (papal legation);
  none to Mayotte or Réunion, as those depend on metropolitan France without full statehood.
