USS James L. Davis was a bark acquired by the Union Navy during the American Civil War.

James L. Davis arrived Cedar Keys, Florida, 2 March and 8 days later captured schooner Florida attempting to slip in through the blockade with a cargo of coffee, soda ash, and other supplies already in short supply in the South.

On 2 October James L. Davis interrupted her blockade duty to serve as a supply ship, carrying stores and provisions to other vessels of the squadron.

The bark continued this essential work until ordered to relieve USS Ethan Allen at St. Joseph's Bay, Florida, in March 1863.
