USS Dart was a captured Confederate schooner acquired by the Union Navy during the American Civil War.

Dart was a small schooner captured by the screw steamer South Carolina off Galveston, Texas, on 4 July 1861.

Though never labeled or purchased by the Navy, she was armed with a 12-pounder howitzer, and cruised as tender to both South Carolina and the screw steamer Huntsville.

During her brief service, she captured several small vessels, including schooners Cecilia on 24 September 1861, and Zavala on 1 October.

Dart was taken out of service, and dismantled by men from the screw frigate Niagara off the southwest pass of the Mississippi River, between 19 and 21 October 1861.
