The Upper Rhine is the section of the Rhine between Basel in Switzerland and Bingen in Germany, surrounded by the Upper Rhine Plain. The river is marked by Rhine-kilometres 170 to 529.

The High Rhine is the name used for the part of the Rhine that flows westbound from Lake Constance to Basel. The High Rhine begins at the outflow of the Rhine from the Untersee in Stein am Rhein and turns into the Upper Rhine in Basel. In contrast to the Alpine Rhine and Upper Rhine, the High Rhine flows mostly to the west.
