Paulinus I was the first Patriarch of Aquileia, serving from 557 to 571.
When the Lombards invaded northern Italy in 568, Paulinus fled Aquileia with his treasures, as had the other Archbishop in schism with Rome, Honoratus of Milan.
Paulinus transferred his see to Grado, a small island opposite Aquileia, which was still controlled by the Byzantines, but retained the title of Patriarch of Aquileia.
He died soon after arriving in Grado.
