Kunz von Kaufungen (also known as Conrad von Kaufungen, or Kunz von Kauffungen; c. 1410 – 14 July 1455) was a German knight and military commander. A veteran of the Hussite wars, he also fought for Frederick II, Elector of Saxony against Frederick's brother Duke William III during the Saxon Fratricidal War (1446–1451). Afterwards, Kunz was not repaid or recognized for his services and loss of property during the war, and eventually during the Prinzenraub (English: "The stealing of the princes") he kidnapped Frederick II's two sons. He was caught and later executed.
