Georg Klindworth, born Johann Georg Heinrich Klindworth on 16 April 1798 in Göttingen, Germany, was a nineteenth-century German diplomat and intelligence agent employed by several European leaders and princes. He was a political exile from the 1848 upheavals, who had worked as a theater agent for two years, later as a lawyer and also as a statesman. He was for many times described as one of the most influential secret diplomats of his time, from the Congress of Vienna to the time of Bismarck.
