Rheinhausen (German pronunciation: [ʁaɪnˈhaʊzən]) is a town in the district of Emmendingen in Baden-Württemberg in Germany.

Rheinhausen is located in the northern Breisgau region on the Rhine river.

Along the Rhine, it includes part of the Taubergießen Nature Reserve, one of the largest nature reserves in Baden-Wuerttemberg.

To the west, across the Rhine river in France, is the Rhinau Island Nature Reserve, in the Schœnau commune of the Bas-Rhin department in France's Alsace region.

In 1972, the town of Rheinhausen was formed by combining two formerly independent communities, now each a village (Dorf), Niederhausen and, to its south, Oberhausen.
