List of Chaldean Catholic patriarchs of Baghdad

This is a list of the Chaldean Catholicoi-Patriarchs of Baghdad, formerly Babylon, the leaders of the Chaldean Catholic Church and one of the Patriarchs of the east of the Catholic Church starting from 1553 following the schism of 1552 which caused a break in the Church of the East, which later led to the founding of the Chaldean Catholic Church.

This list continues from the list of patriarchs of the Church of the East that traces itself back from the Church founded in Mesopotamia in the 1st century and which became known as the Church of the East.

Biblical Aramaic is closely related to Syriac Aramaic, which until recently was called Chaldaic or Chaldee,^[1][2] and East Syrian Christians, whose liturgical language was this dialect of Aramaic, were called Chaldeans,^[3] as an ethnic, not a religious term. Hormuzd Rassam (1826–1910) still applied the term "Chaldeans" no less to those not in communion with Rome than to the Catholic Chaldeans^[4] and stated that "the present Chaldeans, with a few exceptions, speak the same dialect used in the Targum, and in some parts of Ezra and Daniel, which are called 'Chaldee'."^[5]
