The Action of 22 June 1803 was a naval battle between the United States Navy and the Tripolitan Navy during the First Barbary War. Two ships from the American squadron blockading Tripoli, USS John Adams and USS Enterprise, met and engaged a Tripolitan polacre along with nine gunboats. After fighting a sharp action for forty five minutes the gunboats veered off and the polacre was abandoned. The Tripolitians later retook the polacre and were reengaged by the Americans before the vessel was destroyed in a large explosion.
