The Gave de Larrau is a torrential river of the French Basque Country (Pyrénées-Atlantiques), in the southwest of France. It is the left tributary of the river Saison, and considered its upper course by Sandre.^[1] Its name is due to the village of Larrau.

It is formed from the confluence of the Zurkaitzegiko erreka and the Olhadoko erreka. After joining the Uhaitxa, from Sainte-Engrâce, it forms the Saison in Licq-Athérey.

Tributaries: Etxelüko erreka, Ahuntzolako erreka
