The Bidouze,[1] is a left tributary of the Adour, in the French Basque Country (Pyrénées-Atlantiques), in the Southwest of France.


The Bidouze rises at the base of Eltzarreko Ordokia in the Arbailles massif. It drains the east of the Lower Navarre, crossing Saint-Palais (the main town). Then it flows into the Adour in Guiche. Bidouze is one of the reference rivers of minor water volume meandering across the Northern Basque territory along with the Nive and Saison.


The name of the Bidouze can be compared with other Aquitanian placenames as Vidouze (in the northeast of the Hautes-Pyrénées), Bedous or Bidos (both in the Aspe Valley)…
