The Étang de Balistra is a coastal lagoon in the Corse-du-Sud department of France.

There are some meadows with a few cows to the northwest of the lagoon, and a firing range belonging to the Bonifacio military legion to the south.

The lido (sand bar) is used by campers who access it from a track to the south of the lagoon.

In some places there is a narrow belt of spiny rush (Juncus acutus), sea rush (Juncus maritimus) and wheatgrass (Agropyron) between the shrubs and the water, and in the small coves.

There is a reed bed north of the grau where the lagoon drains into the sea.
