USS Fairy was a steamer purchased by the Union Navy during the American Civil War.

Fairy was built in 1861 at Cincinnati, Ohio, as Maria; purchased by the Navy 10 February 1864; and first sailed 10 March 1864, Acting Master H. S. Wetmore in command.

Based at Mound City, Illinois, Fairy patrolled and had convoy duty in the Mississippi, White, and Tennessee Rivers, often providing transportation and firepower to Union Army expeditions, and shelling Confederate troop concentrations and batteries ashore.

On patrol in the Tennessee River, in December 1864 and January 1865, she convoyed Union Army transports from Clifton to Eastport, and carried out other operations in the concerted attack on troops under General John Bell Hood, preventing them from crossing the river near Florence.
