Bigorre is a region in southwest France, historically an independent county and later a French province, located in the upper watershed of the Adour, on the northern slopes of the Pyrenees, part of the larger region known as Gascony. Today Bigorre comprises the centre and west of the département of Hautes-Pyrénées, with two small exclaves in the neighbouring Pyrénées Atlantiques. Its inhabitants are called Bigourdans.

Béarn is one of the traditional provinces of France, located in the Pyrenees mountains and in the plain at their feet, in Southwestern France. Along with the three Basque provinces of Soule, Lower Navarre and Labourd, the Principality of Bidache, as well as small parts of Gascony, it forms the current Pyrénées-Atlantiques department. The capitals of Béarn were successively Beneharnum, Morlaàs, Orthez and then Pau.
