Kazimierz Małachowski of Gryf (1765–1845) was a Polish military officer and a general of both the armed forces of Duchy of Warsaw and the Kingdom of Poland. A recipient of Virtuti Militari for his actions during the Napoleonic Wars, he is best remembered as one of the last Commanders-in-Chief of the failed November Uprising. He assumed command shortly after the disastrous battle of Warsaw.
