Forges-les-Eaux (French pronunciation: [fɔʁʒ le.z‿o]) is a commune in the Seine-Maritime department in the Normandy region in northern France.

[3] A farming and spa town, with considerable light industry, situated by the banks of the rivers Andelle and Epte, in the Pays de Bray, some 34 miles (55 km) southeast of Dieppe, at the junction of the D 915, D 921, D1314 and D 919 roads.

Known as "De Forgis" in 1186, the first part of the name, Forges, is derived from the fact that it was an important centre for the mining and manufacturing of iron in Roman times.

Blanche d'Evreux, widow of Philippe VI of France, came here to take the waters in the fourteenth century, but it was the Chevalier de Varenne who really began the vogue in 1573.

In 1657, the Regent Doctor of the Faculty of Medicine in Paris, Pierre Cressé, wrote a thesis on the waters of Forges which he compared to those of Passy[4] then the chemist Gilles-François Boulduc, apothecary to King Louis XIV, studied their composition.
