Mary of Baux-Orange (died 1417) was suo jure Princess of Orange.
Marie was the only child and therefore the sole heiress of Raymond V of Baux[1] and Joan of Geneva.
On 11 April 1386, she married John III,[1] the son of Louis I, Lord of Chalon-Arlay and Margaret of Vienne.
Mary died in 1417 in Orange and was buried in L'église des Cordeliers at Lons-le-Saunier.
Louis II inherited Chalon-Arlay from his father and Baux-Orange, including the Principality of Orange, from his mother.
