阿杜尔河（法语：Adour）是位于法国西南部的一条河流，发源于比利牛斯山北麓，在巴约讷附近注入大西洋，全长335公里。

The Adour (Basque:Aturri, Occitan:Ador) is a river in southwestern France. It rises in High-Bigorre (Pyrenees), at the Col du Tourmalet, and flows into the Atlantic Ocean (Bay of Biscay) near Bayonne. It is 324 kilometres (201 mi) long, of which the uppermost 15 kilometres (9.3 mi) as the Adour du Tourmalet. At its final stretch, i.e. on its way through Bayonne and a short extent upstream, the river draws the borderline between the Northern Basque Country and Landes regions.
