CSS Wilmington was an unnamed casemate ironclad built for the Confederate States Navy during the American Civil War.

Unlike those ships, Wilmington may have been designed to force engagements on the Union blockaders as her sleek lines and powerful propulsion machinery suggest something more than a defensive role.

[3] The ship's main battery consisted of two guns of an unknown type on pivot mounts,[4] each of which was housed in a small octagonal casemate.

[4] Porter visited Wilmington at the direction of Stephen Mallory, the Confederate States Secretary of the Navy, in late May 1864[6] after the first two ironclads built at Wilmington were lost or became ineffective; Raleigh was run aground and was wrecked on the sandbar at the mouth of the Cape Fear River on 7 May and North Carolina due to the green wood of her hull rotting and attacks by shipworms.

[7] Porter produced his design for Wilmington shortly afterwards and the ship was laid down at the Berry Brothers shipyard on Eagles Island across the river from the city.
