The Clérissy faience factories or ateliers Clérissy were the main pottery factories making Moustiers faience, operated by members of the Clérissy family in Moustiers-Sainte-Marie in the Alpes-de-Haute-Provence, in Marseille, France, and later Varages and elsewhere. Family members continued to produce faïence in different locations until 1733.

Faience or faïence is the general English language term for fine tin-glazed pottery. The invention of a white pottery glaze suitable for painted decoration, by the addition of an oxide of tin to the slip of a lead glaze, was a major advance in the history of pottery. The invention seems to have been made in Iran or the Middle East before the ninth century. A kiln capable of producing temperatures exceeding 1,000 °C (1,830 °F) was required to achieve this result, the result of millennia of refined pottery-making traditions. The term is now used for a wide variety of pottery from several parts of the world, including many types of European painted wares, often produced as cheaper versions of porcelain styles.
