The Lac d'Esparron (French pronunciation: [lak dɛspaʁɔ̃]; English: Lake of Esparron) is an artificial reservoir on the departmental border between Alpes-de-Haute-Provence and Var, Southeastern France.

Its creation flooded the entire plain under Esparron-de-Verdon, as well as raised the level of the river for 8 kilometres (4.9 miles) upstream from the lake.

This had the consequence of cutting the old road leading to Saint-Julien in the Var department and engulfing the bridge, the sole building drowned at the bottom of the lake.

The Lake of Esparron is an important summer tourism centre, frequented for water recreation and for fishing.

On the same shore, near the St Julien beach, is the first of two imposing water intakes that help feed the Canal de Provence.
