Lake Constance (German: Bodensee, pronounced [ˈboːdn̩ˌzeː] ) refers to three bodies of water on the Rhine at the northern foot of the Alps: Upper Lake Constance (Obersee), Lower Lake Constance (Untersee), and a connecting stretch of the Rhine, called the Lake Rhine (Seerhein). These waterbodies lie within the Lake Constance Basin (Bodenseebecken) in the Alpine Foreland through which the Rhine flows.[2][3] The nearby Mindelsee is not considered part of Lake Constance.

The lake is situated where Germany, Switzerland, and Austria meet. Its shorelines lie in the German states of Baden-Württemberg and Bavaria; the Swiss cantons of St. Gallen, Thurgau, and Schaffhausen; and the Austrian state of Vorarlberg. The actual locations of the country borders within the lake are disputed.

The Alpine Rhine forms, in its original course (Alter Rhein), the Austro-Swiss border and flows into the lake from the south. The High Rhine flows westbound out of the lake and forms (with the exception of the Canton of Schaffhausen, Rafzerfeld and Basel-Stadt) the German-Swiss border as far as to the city of Basel.[4][5] The Leiblach forms fhte Austria–Germany border east of the lake.

The most populous towns on the Upper Lake are Constance (German: Konstanz), Friedrichshafen, Bregenz, Lindau, Überlingen and Kreuzlingen. The largest town on the Lower Lake is Radolfzell. The largest islands are Reichenau in the Lower Lake, and Lindau and Mainau in the Upper Lake. Bodanrück, a large peninsula, separates the Upper and Lower Lake.

While in English and in the Romance languages, the lake is named after the city of Constance, the German name derives from the village of Bodman (municipality of Bodman-Ludwigshafen), in the northwesternmost corner of the lake.
