Cactus, a side-wheel steamer, was built during 1863 in Brooklyn, New York, as the Polar Star. She was purchased at New York on 9 December 1863 by the U.S. Navy and was commissioned as U.S.S. Cactus on 4 May 1864 with Acting Master N. Graham in command. She was assigned to the North Atlantic Blockading Squadron with its task of isolating the Confederacy from overseas sources of supply, Cactus served as a supply ship and tender in Hampton Roads until 28 May 1864. She was then ordered up the York River to guard the Army's lines of communication.
On 20 June 1864, with U.S.S. Morse, she fought an engagement with Confederate batteries along the Pamunkey River. After assisting in covering the withdrawal of the Army from White House, Virginia, the steamer returned to Hampton Roads 23 June. Until April 1865, Cactus operated in Hampton Roads and Chesapeake Bay towing launches and supply schooners. She then served in the Potomac Flotilla until placed out of commission at the Washington Navy Yard 8 June 1865. Cactus was transferred to the Light House Board 20 June 1865.
She served in the 2nd Lighthouse District as a supply and inspection tender. She was completely rebuilt in 1870 and was then assigned to the 3rd Lighthouse District. She was refitted in 1882 and again in 1887.
She was decommissioned in 1909 and was eventually sold for $1,025. She became a merchant ship and operated until 1921.
