The viscounts of Béarn (Basque: Bearno, Gascon: Bearn or Biarn) were the rulers of the viscounty of Béarn, located in the Pyrenees mountains and in the plain at their feet, in southwest France. Along with the three Basque provinces of Soule, Lower Navarre, and Labourd, as well as small parts of Gascony, it forms the current département of Pyrénées-Atlantiques (64).
Béarn is bordered by Basque provinces Soule and Lower Navarre to the west, by Gascony (Landes and Armagnac) to the north, by Bigorre to the east, and by Spain (Aragon) to the south.
