Prince of Guémené is a title of French nobility associated with the fiefdom of Guémené-sur-Scorff in Brittany and held within the House of Rohan.
Charles was the founder of the Guémené line of the House of Rohan.
The present male line descendants live in Austria, the family having fled France due to the French Revolution.
In 1816, at the Congress of Vienna, it was decided that the family were the rightful heirs to the duchy which had been the property of the House of La Tour d'Auvergne.
Through the marriage of Jules and Marie Louise de La Tour d'Auvergne in 1743, the Princes of Guémené were descendants of the La Tour d'Auvergne family through Marie Louise, whose nephew Jacques de La Tour d'Auvergne (son of her brother the Duke of Bouillon and Mademoiselle de Marsan) was the last Duke of Bouillon.
