The Provisional Government Commission of the Grand Duchy of Lithuania; also, the Lithuanian Provisional Governing Commission (Lithuanian: Lietuvos laikinosios vyriausybės komisija; also Lietuvos Didžiosios Kunigaikštystės vyriausybės komisija, Polish: Komisja Rządu Tymczasowego Wielkiego Księstwa Litewskiego; also Komisja Rządząca Tymczasowa Litewska; French: Gouvernement provisoire de Lituanie; also Gouvernement général de la Lituanie) was a provisional administrative body for Lithuania, which had been overtaken by Napoleon's Grand Army during the 1812 French invasion of Russia.
