The Chaldean Catholic Archeparchy (or Archdiocese) of Baghdad is the Metropolitan, proper Archeparchy of the Chaldean Catholic Patriarch of Babylon, with cathedral see in the Iraqi capital Baghdad.
As the Patriarch is its Metropolitan Archeparch, it has no other Ordinary of its own.
It was established on 20 April 1553 as the Metropolitan Archdiocese of Baghdad (Latin Babylonen[sis] Chaldæorum) of the Chaldean Catholic Church, an Eastern Catholic Church using the Syro-Oriental Rite in the Chaldean language.
On 17 January 1954, it lost territory to establish the Chaldean Catholic Archdiocese of Bassorah (Archeparchy of Basra), in southern Iraq.
