The Principality of Orange was, from 1163 to 1713, a feudal state in Provence, in the south of modern-day France, on the east bank of the river Rhone, north of the city of Avignon, and surrounded by the independent papal state of Comtat Venaissin.

Orange is a commune in the Vaucluse department in the Provence-Alpes-Côte d'Azur region in Southeastern France. It is about 21 km (13 mi) north of Avignon, on the departmental border with Gard, which follows the Rhône and also constitutes the regional border with Occitania. Orange is the second-most populated city in Vaucluse, after Avignon.
