USS Connecticut was a large steamer acquired by the Union Navy during the American Civil War.

Connecticut sailed on her first voyage 25 August 1861, delivered men and supplies to ships on the blockade along the Atlantic and Gulf coasts as far as Galveston, Texas, and returned to New York 29 September.

Included were the English steamer Minnie, captured 9 May 1864 with a cargo of cotton, tobacco, turpentine, and gold, one of the most valuable prizes taken during the war; and the British steamer Greyhound, taken on 10 May, which carried in addition to her cargo of cotton, tobacco, and turpentine, the famous Confederate spy Belle Boyd.

Her last cruise from 21 February to 3 August 1865 was in the West Indies and on the U.S. East Coast, searching for Confederate privateers and towing monitors from Port Royal, South Carolina, to Philadelphia, Pennsylvania.
