Hüfingen (Low Alemannic: Hifinge) is a town in the district of Schwarzwald-Baar, in Baden-Württemberg, Germany.

In the first century of the common era, imperial policy settled on using the natural boundaries formed by the Danube and the Rhine rivers.

Because of its proximity to the source of the Danube in nearby Donaueschingen, Hüfingen was the site of a Roman fort, Brigobanne, built to implement this policy.

The legions built a road to Hüfingen from what is now Schleitheim, on the upper Rhine in Switzerland, thus connecting the two rivers with a man-made line on the landscape, defining a continuous border.
