Cadouin Abbey was a Cistercian monastery founded as a hermitage in 1115 by Gerald of Salles, in the name of Robert of Arbrissel, in what is now the commune of Le Buisson-de-Cadouin in the Dordogne, south-west France.
In 1119 Cadouin was made an abbey under its first abbot, Henri, a monk of Pontigny Abbey, the second daughter house of Cîteaux Abbey, but seems to have remained independent of the Cistercian Order until around 1199.
Cadouin founded daughter houses of its own which also became Cistercian, not necessarily at the same time as Cadouin itself.
