The Chaldean Catholic Archeparchy (or Archdiocese) of Basra (or Bassorah) is a non-metropolitan Archeparchy (Eastern Catholic archdiocese) of the Chaldean Catholic Church (Syro-Oriental Rite, Syriac or Aramaic language) in southern Iraq.

It is subject to the Chaldean Catholic Patriarch of Babylon, without suffragan.

Its cathedral episcopal see Cathedral of Our Lady, is in Al Basrah.

In 280 AD it was established as Diocese of Perat-Maishan (Perâth Maishân), which was promoted in 410 to the Metropolitan Archdiocese of Perat-Maishan. It was suppressed in 1200.

In 1860 it was nominally restored as Titular archbishopric of Perat-Maishan, and was again suppressed in 1895.

On 17 January 1954, it was fully restored as residential Chaldean Catholic Archeparchy of Basra (Bassorah), on territory split off from the Metropolitan Chaldean Catholic Archeparchy of Baghdad.
