The Bergse Maas (pre-1947 spelling: Bergsche Maas) is a canal that was constructed in 1904 to be a branch of the Maas River (French: Meuse) in the Dutch province of North Brabant. The Maas splits near Heusden into the Afgedamde Maas and the Bergse Maas. The Afgedamde Maas flows north until its confluence with the river Waal (the main distributary of the river Rhine) to form the Merwede, while the Bergse Maas continues west as the main distributary of the Maas. Part of the Merwede (the Nieuwe Merwede) rejoins the Bergse Maas to from the Hollands Diep estuary.
