The Provisional Government Commission of the Grand Duchy of Lithuania; also, the Lithuanian Provisional Governing Commission was a provisional administrative body for Lithuania, which had been overtaken by Napoleon's Grand Army during the 1812 French invasion of Russia. Because of that fact, the entity is sometimes called Napoleonic Lithuania. On 14 July 1812 the Commission formally joined the General Confederation of the Kingdom of Poland, creating the united Kingdom of Poland.
