The sidewheel steamer Mackinaw, built at the New York Navy Yard in 1863, was launched 22 April 1863, and commissioned at New York 23 April 1864, Comdr. J. C. Beaumont in command.

Mackinaw joined the North Atlantic Blockading Squadron, starting picket duty on the James River in May and remaining on the river for most of 1864. She destroyed the steamer Georgiana McCaw 5 June [1864] and supported Union troops on their advance from Dutch Gap, Va., 11 August [1864].

Transferred to the Wilmington blockade, Mackinaw chased a steamer 7 November and captured schooner Mary east of Charleston 3 December. She participated in the attacks on Fort Fisher 24 and 25 December and 13 and 14 January 1865. She went into action against Fort Anderson 18 February, shelling the works at Port Royal until the latter part of April. She was ordered to Portsmouth, N.H., 26 April and decommissioned 11 May.
