USS Mingoe was a large double-ended, side wheel, ironclad[1] steamer gunboat commissioned by the Union Navy during the American Civil War.

With heavy guns and a very fast speed of 11 kn (13 mph; 20 km/h), the ship was intended by the Union Navy for use as a bombardment gunboat.

An ironclad, side wheel, steam gunboat, with schooner rigging, Mingoe was built under contract with Daniel S. Mershon, Jr. at Bordentown, New Jersey, at a shipyard located along the Delaware River.

[2] The ship was named after the Mingo people, an Iroquoian-speaking group that had been based in western Ohio in the early nineteenth century.

In February 1865, the Navy used her to assist General William Tecumseh Sherman's Army in its advance up the James River.
