The Scarpe (French pronunciation: [skaʁp]) is a river in the Hauts-de-France region of France.

The navigable waterway and its coal barges also feature in the novels by 19th century author Émile Zola.

This river was navigated from the Escaut up to Douai as early as 638, but improvements with flash locks were required to give access to the important town of Arras, reached in 1613.

This remained a shallow navigation, with locks of varying width and length, until it was improved to the Becquey gauge in the 1840s.

Today the Lower Scarpe is closed from the Douai junction to Saint-Amand-les-Eaux pending dredging and identification of a new owner and operator.
