Arnéguy (in French pronounced as /aʁneɡi/; Basque: Arnegi) is a commune in the Pyrénées-Atlantiques department in southwestern France. The village is an important stopping point on the road between Saint-Jean-Pied-de-Port and Pamplona, Spain, as it lies on the border of France and Spain. It is located in the former province of Lower Navarre. Because of its proximity to Saint-Jean-Pied-de-Port, Arnéguy is a popular tourist destination for those travelling across the Pyrenees, although its economy remains mostly agricultural.
