USS Lilian was a large steamer captured by the Union Navy during the American Civil War.

Lilian, an iron wide-wheel steamer built on the Clyde River, Scotland, in 1863, was captured some 100 miles east of Cape Fear, North Carolina, 24 August 1864 by USS Keystone State and other Union ships.

Among the prisoners were five Wilmington, North Carolina, pilots being carried to Bermuda to guide Confederate ships through the blockade.

Lilian joined the fleet attacking Fort Fisher, Cape Fear River, 23 to 24 December 1864 and 13 to 14 January 1865.

After this attack, she patrolled the inlet, and with USS Tristram Shandy captured the British steamer Blenheim 25 January.
