Prince Józef Klemens Czartoryski (1740–1810) was a Polish nobleman (szlachcic) who owned Korets Castle.
He was a Knight of the Order of the White Eagle, awarded in 1767.
He became the Great Stolnik of Lithuania in 1764, Klucznik (Steward) of Volhynia in 1772 and Starost and Wójt of Luki and Radoszyce.
He produced faience and porcelain at his estate, until the manufactory burnt down.
After 1797, he was engaged in making Kontusz sashes (Pas kontuszowy), for the nobility.
From 1789 to 1790 he was the Polish envoy in Berlin and was heavily involved in forging the Polish–Prussian alliance.
