The Amer is a river in the Dutch province of Noord-Brabant. It is a continuation of the Bergse Maas river from the river Donge near Raamsdonksveer to the point where it joins the river Nieuwe Merwede to form the Hollands Diep estuary, and has a total length of approximately 20 kilometres (12 mi). The Amer is a major navigation route. It forms the south boundary of the Biesbosch National Park.
The river is also known because the Amercentrale, one of the biggest power plants in the Netherlands, is located on its bank. As a result, ships transporting coal for the plant use the eastern part of the river, mainly coming from the Wilhelminakanaal.
