Yolande, Duchess of Lorraine, also known as Yolande de Bar (2 November 1428, Nancy – 23 March 1483, Nancy), was Duchess of Lorraine (1473) and Bar (1480). She was the daughter of Isabella, Duchess of Lorraine, and René of Anjou (King of Naples, Duke of Anjou, Bar and Lorraine, Count of Provence). Because of her various titles she is also known as Yolande de Lorraine and Yolande d'Anjou. Her younger sister was Margaret of Anjou, Queen consort of Henry VI of England. Though she was nominally in control of major territories, she ceded her power and titles to her husband and her son.
