Prince Karl Anton of Hohenzollern-Sigmaringen (German: Karl Anton Joachim Zephyrinus Friedrich Meinrad Fürst von Hohenzollern-Sigmaringen) (7 September 1811 – 2 June 1885) was the final Prince of Hohenzollern-Sigmaringen before the territory was annexed by Prussia in 1849 and Prime Minister of Prussia from 1858 to 1862, which made him the only Hohenzollern Prince to hold that post.
Because of the Revolutions of 1848, Constantine, Prince of Hohenzollern-Hechingen and Karl Anton, Prince of Hohenzollern-Sigmaringen abdicated their thrones in December 1849. The principalities were ruled by the Kings of Prussia from December 1849 onwards, with the Hechingen and Sigmaringen branches obtaining official treatment as cadets of the Prussian royal family.
Karl Anton's second son, Karl Eitel of Hohenzollern-Sigmaringen became prince (1866–1881) and then King of Romania, under the name Carol (reigned 1881–1914). The house remained on the throne until the end of the Romanian monarchy in 1947.
