The Abbey of Saint-Léonard des Chaumes (Latin: Sanctus Leonardus de Calmis)[1] was a Cistercian monastery in Dompierre-sur-Mer in the province of Aunis in the Kingdom of France.

The establishment was originally poor —chaumes meant "uncultivated land" in Old French.

[3] In 1168, the establishment, which had been a priory for a century, joined the Cistercian Order and became a daughter house of Bœuil Abbey in Limousin.

Vincent de Paul briefly served as commander of the abbey from 1610.

At this time, the commendatory regime and the war (the first Siege of La Rochelle) already had visible negative consequences.
