The Nieuwe Maas (Dutch pronunciation: [ˌniu.ə ˈmaːs]; "New Meuse") is a distributary of the Rhine River, and a former distributary of the Maas River, in the Dutch province of South Holland. It runs from the confluence of the rivers Noord and Lek, and flows west through Rotterdam. It ends west of the city where it meets the Oude Maas ("Old Meuse"), near Vlaardingen, to form Scheur. After a few miles, the Scheur continues as the artificial Nieuwe Waterweg. The total length of the Nieuwe Maas (excluding the Scheur) is approximately 24 kilometres (15 mi).
