Sare (French pronunciation: [saʁ]; Basque: Sara)[3] is a village and a commune in the Pyrénées-Atlantiques department in south-western France on the border with Spain.

The summit of La Rhune, a mountain iconic of the Basque country, is situated approximately 4 km (2.5 mi) to the west of the village.

Today, its territory forms an enclave in the Navarre, a region of Spain, with which it shares a 25 km (16 mi) border.

During the Peninsular War the Anglo-Portuguese Army led by the future Duke of Wellington breached the frontier and repelled the French troops who had stationed themselves in forts on La Rhune.

Agricultural activity remains a constant element of the town's economy, even though the location has hosted mining industries since the Middle Ages, and more recently a wool treatment mill.
