USS Mingoe (1863) was a large steamer purchased by the Union Navy during the American Civil War. With her heavy guns, she was planned by the Union Navy for use as a bombardment gunboat, but also as an interceptor gunboat stationed off Confederate waterways to prevent their trading with foreign countries. A side wheel steam gunboat, Mingoe was built under contract with D. S. Mainthon at Bordentown, New Jersey; was launched 6 August 1863; and commissioned 29 July 1864 at Philadelphia, Pennsylvania, Comdr. J. B. Creighton in command.
