USS Don was a captured British steam-operated cargo ship acquired by the Union Navy from the prize court during the American Civil War.

She was put into service by the Union Navy to patrol navigable waterways of the Confederacy to prevent the South from trading with other countries.

The British blockade runner Don was captured off Beaufort, North Carolina on 4 March 1862 by Pequot, and sent to Boston, Massachusetts for adjudication.

She patrolled the Potomac River and other waters in and bordering Virginia with her base at Washington Navy Yard until 26 September 1865, when she sailed for New York City.
