Arget is a French commune in the Pyrénées-Atlantiques department in the Aquitaine region of south-western France.
The inhabitants of the commune are known as Argétois or Argétoises.
Arget is located some 18 km north-east of Orthez and 12 km south-east of Hagetmau on the border between Pyrénées-Atlantiques and Landes departments. It can be accessed by the D264 road from Montagut in the east passing through the commune and the village (of 2 buildings) and continuing south-west to Casteide-Candau. The commune has quite large areas of forest in the west but is mostly farmland.
Several streams rise in the commune with the Hourquet forming the north-western border as it flows north-east to join the Ruisseau de la Rance at the northern tip of the commune. The Rance forms the north-eastern border as it flows north-west. The south-eastern border also consists of an unnamed stream which joins the Rance just outside the eastern tip of the commune.
