Arette (Areta in Occitan) is a commune in the Pyrénées-Atlantiques department in south-western France. It is located in the arrondissement of Oloron-Sainte-Marie and is one of the six communes of the canton of Aramits; the other five are Ance, Aramits (commune), Féas, Issor et Lanne-en-Barétous. Arrete lies close to both the French Basque region and to Spain, and is within the borders of Béarn, one of the traditional French provinces.

Arette is a very large commune and has a land area of 92 km². It is also mountainous (the La Pierre Saint-Martin ski resort is within its borders, for example) and its highest peak is the 2,315 m Soum Couy, which is situated not far from the 2,504 m Pic d'Anie: the highest peak in the western Pyrenees. From Pic d'Anie the mountain range extends downwards for approximately 20 km, forming both sides of the Aspe valley to the north-west. The Vert d'Arette (a tributary of the Vert) flows through this valley. The ancient village (also named Arette) from which the commune extends is located at an altitude of 316 m in the valley of Barétous, which lies between the aforementioned Aspe valley, to its east, and the Basque province of Soule, to its west.
