Jean-Baptiste Drouet was a French politician of the Revolution and the Empire, best known for his key role in the arrest of King Louis XVI and his family during the Flight to Varennes.

The royal Flight to Varennes during the night of 20–21 June 1791 was a significant event in the French Revolution in which King Louis XVI of France, Queen Marie Antoinette, and their immediate family unsuccessfully attempted to escape from Paris to Montmédy, where the King wished to initiate a counter-revolution by joining up with royalist troops. They escaped as far as the small town of Varennes-en-Argonne, where they were arrested after being recognized at their previous stop in Sainte-Menehould.
