Fontfroide Abbey (French: Abbaye Sainte-Marie de Fontfroide; Latin: Fons frigidus) is a former Cistercian monastery in France, situated 15 kilometers south-west of Narbonne near to the Spanish border.

It was founded in 1093 by Aimery I, Viscount of Narbonne, but remained poor and obscure, and needed to be refounded by Ermengarde, Viscountess of Narbonne.[1] In 1144 it affiliated itself to the Cistercian reform movement.[1] Shortly afterwards the Count of Barcelona gave it the land in Spain that was to form the great Catalan monastery of Poblet, of which Fontfroide counts as the mother house, and in 1157 the Viscountess Ermengard of Narbonne granted it a great quantity of land locally, thus securing its wealth and status. The abbey fought together with Pope Innocent III against the heretical doctrine of the Cathars who lived in the region. It was dissolved in 1791 in the course of the French Revolution.

It was re-founded in 1858 by monks from Sénanque Abbey. The community was driven out of France by French legal changes in 1901. The premises, which are of very great architectural interest, passed into private hands in 1908, when the artists Gustave and Madeleine Fayet d'Andoque bought it to protect the fabric of the buildings from an American collector of sculpture. They restored it over a number of years and used it as a centre for artistic projects.
