USS Keystone State was a wooden sidewheel steamer that served in the Union Navy during the American Civil War. She was a fast ship for her day and was used effectively to blockade Confederate ports on the Atlantic coast. She participated in the capture or destruction of 17 blockade runners. In addition to her military service, Keystone State had a lengthy commercial career before the war. Renamed San Francisco, she also sailed commercially after the war. The ship was built in 1853 and scrapped in 1874.
