Waldburg-Waldsee was a County and later Principality within Holy Roman Empire, ruled by the House of Waldburg, located in southeastern Baden-Württemberg, Germany, around Bad Waldsee. Waldburg-Waldsee was a partition of Waldburg-Wolfegg. When the Wolfegg branch extinguished in 1798, the Waldsee branch inherited Wolfegg. Waldburg-Waldsee was a county prior to 1803, when it was raised to a principality shortly before being mediatised to Württemberg in 1806. The castle of the princes of Waldburg-Waldsee lies in the town of Kißlegg.
