USS Cohasset (1860) was a tugboat acquired by the Union Navy during the American Civil War. She was used by the Union Navy for various purposes: as a tugboat, dispatch vessel, escort vessel, and even as a gunboat. Cohasset — a tug originally called E. D. Fogg and later Narragansett — was built in 1860 at Providence, Rhode Island; purchased by the Navy on 13 September 1861; outfitted at New York Navy Yard; delivered at Hampton Roads, Virginia on 26 October 1861; and assigned to duty with the Atlantic Blockading Squadron, Pilot Thomas Evans in command.
