Karl Freiherr von Vincent (11 August 1757 – 7 October 1834) fought in the army of Habsburg Austria during the French Revolutionary Wars.

He was governor-general of Belgium in 1814, and was present at the Battle of Waterloo as an Austrian observer.

Between 1814 and 1826, von Vincent was the Austrian ambassador to France at the Tuileries during the shift in the European political equilibrium of 1820.

[1] He was also cited in an account describing Klemens von Metternich's proposals concerning the fate of Belgium.

He was identified as a candidate in charge of its occupation but it was noted that his office was under the authority of Baron Stein's administrative department when it came to political matters and that he must also defer to the Dutch, English, and Prussians in the area of military affairs.
