The Lys (French) or Leie (Dutch) is a river originating in France, entering Belgium and flowing through the city of Kortrijk into the river Scheldt in Ghent. Its total length is 202 km.

It is a very polluted river due to the high density of population and industry in the North of France and in Belgium. Historically, the Lys valley was known for the spinning and weaving of flax. The region of the Leie (between Deinze and Ghent) used to be known as a favourite place for numerous painters in the first half of the twentieth century.
