The Oude Maas (Dutch pronunciation: [ˌʌudə ˈmaːs]; English: Old Meuse) is a distributary of the river Rhine, and a former distributary of the river Maas, in the Dutch province of South Holland. It begins at the city of Dordrecht where the Beneden Merwede river splits into the Noord and the Oude Maas. It ends when it joins the Nieuwe Maas to form Het Scheur.
