Leopold, Prince of Hohenzollern (German: Leopold Stephan Karl Anton Gustav Eduard Tassilo Fürst von Hohenzollern; 22 September 1835 – 8 June 1905) was the head of the Swabian branch of the House of Hohenzollern, and played a fleeting role in European power politics, in connection with the Franco-Prussian War. He was born into the dynasty's Sigmaringen branch, which inherited all the dynasty's Swabian lands when the Hohenzollern-Hechingen branch became extinct.
