The USS Circassian was an iron screw steamer that served in the Union Navy during the American Civil War. Originally a civilian vessel, she was captured by the Union ship USS Somerset on May 4, 1862, and subsequently purchased from the prize court at Key West, Florida, on November 8, 1862. After being outfitted at the New York Navy Yard, she was commissioned on December 12, 1862, under the command of Acting Volunteer Lieutenant W. B. Eaton. Designed as a large steamer, the USS Circassian functioned primarily as a supply ship for the Union blockade operations along the Confederate States' ports and waterways. Her service record includes nine cruises between December 1862 and April 1865, operating from bases such as New York City and Boston. She supplied ships and stations along the Atlantic coast, the Gulf of Mexico, and as far west as Galveston, Texas, and up the Mississippi River to New Orleans. On her return voyages, she transported discharged personnel, invalids, prisoners of war, cotton, and provisions. Throughout her service, the USS Circassian was actively involved in various notable events. She captured two prizes during her patrols and participated in the search for the Confederate steamer Florida in July 1864. On September 3, 1864, off Sabine Pass in the Gulf of Mexico, she rescued nine crew members from the wrecked U.S. steamer Gillum, which had been lost en route from New Orleans to Matamoros, Mexico. Her operational contributions extended to multiple theaters of the Civil War, supporting Union efforts to blockade and control Confederate waterways. The USS Circassian arrived back at Boston Navy Yard on April 11, 1865, marking the end of her commissioning period. She was decommissioned on April 26, 1865, and sold on June 22, 1865. Her service as a supply vessel and her participation in wartime operations underscored her maritime significance during the Civil War.
