USS Dacotah (1859) – the only United States Navy ship to be so named – was a large (996 long tons (1,012 t)) steam sloop that served the United States Navy in the Atlantic Ocean as well as in Pacific Ocean. When the American Civil War occurred, Dacotah assumed the role of a gunboat in the Union blockade of the Confederate States of America.
When the war was over, Dacotah – who was named for the American Dakota tribe – resumed her role protecting American interests worldwide by showing her presence in both the Atlantic and Pacific Oceans.
Launched at Norfolk, Virginia, in 1859

Sailing from Norfolk, Virginia on 30 June 1860, Dacotah rounded the Cape of Good Hope, and arrived at Hong Kong on 8 January 1861 to join the East Indian Squadron. She cruised off China until returning to Hong Kong on 14 June. On 6 August, she sailed for home and arrived at St. Thomas, Virgin Islands on 21 November for two weeks of patrolling before arriving at New York City on 20 December.

From 19 July, she was assigned to the James River Flotilla. She had several skirmishes with the Confederates including those in which a company of her sailors and marines, destroyed a Confederate battery of 11 guns at Harden's Bluff, Virginia on 2 July, and one of 15 guns at Day's Point, Virginia the next day.

Ordered to Nassau, Bahamas on 4 September to search for the Confederate privateers Alabama and Florida, she patrolled off the Bahamas until 1 November, when she was sent to search further northward to Newfoundland and Nova Scotia.
Returning to the blockade on 15 September she was ordered into quarantine at New York City the next month when several cases of smallpox were discovered on board. During a repair period at Portsmouth, New Hampshire, she participated in the search for the captured steamer-turned-raider Chesapeake from 13 to 23 December.
