Ursula of Pfirt

Ursula of Pfirt (died after 5 May 1367) was the daughter of Count Ulrich III of Pfirt, and a younger sister of Joanna of Pfirt, wife of Duke Albert II of Austria. In 1333 she and her husband Count Hugo I of Hohenberg-Rotenburg renounced their rights to the County of Ferrette, and between 1347 and 1351 she held the lordships of Belfort and Rougemont.

After Hugo died on 26 May 1354 she married Count William II of Montfort-Bregenz. Her daughter, also named Ursula, married William's son Count William III and later Eberhard IV of Lupfen.
