The Catholic Church of Iraq has no national (Latin) episcopal conference, but is united in an inter-rite Assembly of the Catholic Bishops of Iraq, given its diversity :

• a Latin non-Metropolitan Archdiocese (participation in the transcontinental Arab Region Latin Bishops conference)
• divided over four Eastern Catholic rite-specific particular churches : a Patriarchate, two Metropolitan - and six other archeparchies, three more eparchies and two (pre-diocesan) Patriarchal exarchates.

There is an Apostolic Nunciature to Iraq in the national capital Baghdad, as papal diplomatic representation at embassy-level (Established as Apostolic Delegation of Mesopotamia, Kurdistan and Lesser Armenia, in 1937 renamed as Apostolic Delegation of Iraq, promoted on 1966.10.14), into which is also vested the Apostolic Nunciature to neighbouring (Trans)Jordan.
