Chaldean Catholic Archeparchy of Mosul, Catholic Archieparchy in Mosul, Iraq.

The Chaldean Catholic Archeparchy of Mosul is a diocese of the Chaldean Catholic Church whose territory is the city of Mosul, subdivided into 12 parishes. Its followers are ethnic Assyrians who speak Neo-Aramaic. The archbishop is concurrently pastor of St. Paul's Cathedral, which was badly damaged by a bombing on December 7, 2004.

The archeparchy was established in 1967 when Pope Paul VI elevated the former Diocese of Mosul to a higher ecclesiastical rank within the Chaldean Catholic Church. This change reflected growing pastoral needs in the region.

This ecclesiastical jurisdiction serves as a spiritual center for the Chaldean Catholic Assyrian community, where Neo-Aramaic language and religious traditions remain woven into daily worship and communal life.

The archeparchy's seat is St. Paul's Cathedral in the Hai Al-Majmou'a area of Mosul; the archbishop's residence stood 10 km away and was destroyed by attackers on 12 August 1995. The cathedral itself was badly damaged by a bombing on 7 December 2004. Check access conditions before travelling, as the city's Christian areas have changed greatly since 2003.

The current leader, Archbishop Najib Mikhael Moussa, has guided the jurisdiction since 2018 and continues the work of his predecessors. Under his leadership, the archeparchy works to support and maintain the community's traditions.
