Laruns (French pronunciation: [laʁœ̃s];[3][4][5] Occitan: Laruntz) is a commune in the Pyrénées-Atlantiques department in south-western France.

[7] Formerly part of the province of Béarn, Laruns is now within the département of Pyrénées-Atlantiques, itself in France's Nouvelle-Aquitaine région.

It includes a large area of upland, around and between the Gave d'Ossau and its tributaries, stretching as far as the border with Spain at the Col du Pourtalet, 30 km (19 mi) to the south of the village of Laruns.

The principal artery of communications through the commune is the D934 road, which runs south from the town of Pau, 40 km (25 mi) to the north, to the Col du Pourtalet.

The D918 road branches off the D934 in Laruns village, and follows the Valentin before crossing the Col d'Aubisque to Argelès-Gazost in the next major valley to the east.
