Ulrich II von Treven was Patriarch of Aquileia in northern Italy from 1161 to 1181. He supported Frederick I, Holy Roman Emperor, (1122–1190) in his unsuccessful struggle for supremacy over the northern Italian states and the papacy. He was also involved in a dispute over jurisdiction with the Patriarch of Grado where he was ultimately successful.
