Le Sauze-du-Lac (French pronunciation: [lə soz dy lak], literally Le Sauze of the Lake; Occitan: Lo Sause dau Lac, before 1991: Le Sauze)[3] is a commune in the Hautes-Alpes department in southeastern France.

Situated below the Pic du Morgon mountain, Le Sauze du Lac lies on a promontory sticking out between the two sides of the Lac de Serre-Ponçon.

This used to be the meeting point, or confluence, of the Ubaye and Durance rivers.

The village is located 9.1km south east of Savines-le-Lac, and 20.6km from the capital of the departement, Gap, Hautes-Alpes.

The village was moved after its original site was flooded by the lake in the early 1960s.
