USS Fort Morgan was a steamer acquired by the Union Navy during the American Civil War.

Fort Morgan, a screw steamer, was built in 1863 by S. H. Pook, Fair Haven, Connecticut, as Admiral; purchased 8 January 1864; and commissioned as Admiral 5 February 1864, Acting Volunteer Lieutenant W. B. Eaton in command.

As storeship for the ships of the Gulf Blockading Squadrons, the steamer sailed from New York City and other east coast ports with provisions, munitions, passengers, and general stores for ships on station between Key West, Florida, and Galveston, Texas.

Several times while making passage from one port to another on this duty she gave chase to blockade runners, capturing steamer Ysabel out of Havana, Cuba, 28 May 1864, and two small schooners in November.
