Schwarzburg-Sondershausen was a small principality in Germany, in the present day state of Thuringia, with its capital at Sondershausen.


Schwarzburg-Sondershausen was a county (earldom) until 1697. In that year, it became a principality, which lasted until the fall of the German monarchies in 1918, during the German Revolution of 1918–1919. After the German Revolution, it became a republic and joined the Weimar Republic as a constituent state. In 1920, it joined with other small states in the area to form the new state of Thuringia.

Schwarzburg-Sondershausen had an area of 862 km2 (333 sq. mi.) and a population of 85,000 (1905). Towns placed in the state were: Arnstadt, Sondershausen, Gehren, Langewiesen, Großbreitenbach, Ebeleben, Großenehrich, Greußen and Plaue.
