Hugh (or Hugo) (c. 780 – 20 October 837) was the count of Tours and Sens during the reigns of Charlemagne and Louis the Pious, until his disgrace in February 828.

He is probably a son of Count Luitfrid II d'Alsace of the House of the Etichonen and Hiltrude, daughter of Carloman Martel.

His wife is Ava of Paris.
