List of Catholic dioceses in Ethiopia and Eritrea

The Catholic Church in Ethiopia and Eritrea is joined in a single transnational episcopal conference which, also atypically, includes the Eastern Catholic (Coptic) churches, totaling of two metropolitan archeparchies, six diocesan suffragans (eparchies) and nine pre-diocesan Latin missionary jurisdictions (apostolic vicariates, except one apostolic prefecture). Each country also has an inter-Catholic national assembly.
 * The Latin hierarchy is composed solely of the pre-diocesan missionary jurisdictions in Ethiopia.
 * The Eastern Catholics have a Coptic (Alexandrian Rite) particular church sui iuris in each country (both using the Archaic Geez language), each headed by a metropolitan whose ecclesiastical province, covering that nation, is the whole church, with three suffragans each.

Furthermore, there is an Apostolic Nunciature to Ethiopia (papal embassy-level diplomatic representation) in the national capital Addis Abbeba; in it are also vested the Apostolic Nunciatures to Djibouti and to Somalia. The Apostolic Nunciature to Eritrea is vested in the Apostolic Nunciature to Sudan (in its capital Khartum)
