Jean Baptist, Comte d'Arco (German Johann Baptist, Graf von Arco) (c. 1650 – 21 March 1715, Munich) was a diplomat and Generalfeldmarschall in the service of the Electorate of Bavaria during the Great Turkish War and the War of the Spanish Succession. He should not be confused with his contemporary Johann Philipp d'Arco, who fought on the opposite (Austrian) side in the latter conflict.
