The Léez (Leez, Lées, Léès, Lees) is a left tributary of the Adour, in the Southwest of France. It is 56.2km (34.9miles) long.
This name proceeds from an Aquitanian hydronym Lez / Liz.
The Léez rises near Gardères in the north of the plateau of Ger. It flows north through the Vic-Bilh area in the east of the Pyrénées-Atlantiques and joins the Adour in the French département of the Gers, upstream from Aire-sur-l'Adour.
