USS Sea Bird was a captured Confederate schooner acquired by the Union Navy from the prize court during the American Civil War.

Sea Bird—a schooner captured by Union side wheel steamer DeSoto on 13 May 1863—was purchased by the Navy on 12 July 1863 from the Key West, Florida, prize court.

The ship was soon fitted out at Key West and commissioned there either in late July or in early August, Acting Master Charles P. Clark in command.

In July 1864, Sea Bird and three other small sailing ships carried Union troops and landed them for a raid on Brookville, Florida.

After disembarking the soldiers, Sea Bird and USS Ariel proceeded to Bayport, Florida, where a landing party captured a quantity of cotton and burned the customs house before returning to Anclote Keys.
