The Fontaine de Vaucluse (French pronunciation: [fɔ̃tɛn də voklyz]) is a karst spring in the commune of Fontaine-de-Vaucluse, France. It is the largest karst spring in metropolitan France by flow and fifth largest in the world, with an annual output of 630,000,000 to 700,000,000 cubic metres (2.2×1010 to 2.5×1010 cu ft) of water.
