List of bishops and patriarchs of Aquileia

This is a list of bishops and Archbishops of Aquileia in northeastern Italy. For the ecclesiastical history of the see, see Patriarchate of Aquileia .

From 553 until 698 the archbishops renounced Papal authority and when they returned to the Roman fold they maintained the title patriarch they had assumed during this schism.

The Patriarchs gained the Countship of Friuli and the March of Carniola in 1077 and the March of Istria in 1209. The temporal authority of the patriarch was lost on 7 July 1420 when its territories were secularized by Venice.

The Patriarchate was dissolved in 1752 and its ecclesiastical authority divided between the Archbishop of Gorizia and the Archbishop of Udine.
