George of Austria (Gent, 1505 – Liège, May 4, 1557), was Prince-bishop of Liège between 1544 and 1557.
He was an illegitimate son of Maximilian I, Holy Roman Emperor and Margaretha of Edelsheim. He became Bishop of Brixen (Tyrol) between 1525 and 1537 and Archbishop of Valencia between 1538 à 1544.
In 1544 he became Prince-bishop of Liège by the influence of his nephew Charles V, Holy Roman Emperor, a post he held until his death. George strongly opposed any French influence in the Prince-Bishopric of Liège, thus maintaining the strong grip of the Habsburgs, who controlled all surrounding lands.
In 1554, he was faced with an French invasion under King Henry II of France.
