Fürstenberg was a county (German: Grafschaft), and later a principality (Fürstentum), of the Holy Roman Empire in Swabia, which was located in present-day southern Baden-Württemberg, Germany.

Over the centuries, the various rulers expanded their territories to include the Landgraviate of Baar, the County of Heiligenberg, the Lordships of Gundelfingen, Hausen, Höwen, and Meßkirch, and the Landgraviate of Stühlingen in Germany, as well as domains around Křivoklát Castle (German: Pürglitz), Bohemia, Tavíkovice (German: Taikowitz) in Moravia and Weitra in Austria.

The five larger parts were: The smaller exclaves included the towns of Ennabeuren, Salmendingen, Neufra, Trochtelfingen, Hayingen, and others.

(Note: The analysis given here will go further back to the origins of the Counts of Urach/Freiburg, from which the Fürstenbergs descended in direct line, and with which shared the coats of arms and still exchanged property in the 13th century.

Weitra line extinct, possessions fell back to Prince Maximilian Egon II as head of the House of Fürstenberg.
