USS Scorpion was a self-propelled floating artillery battery in commission with the United States Navy from 1812 to 1814. Scorpion was sloop-rigged and could also be propelled by oars. She probably was built under contract for the U.S. Navy in 1812 for service during the War of 1812. Lieutenant Edmond P. Kennedy assumed command of the ship at Norfolk, Virginia, in September 1812. For more than a century, the remains of some of the flotilla were visible in the Patuxent River mud. But by the mid-20th century they had vanished, thanks to salvage hunters and the river silt.
