USS Thunder was a blockade running steamer captured by the Union Navy during the American Civil War.

Blockade runner, Annie Dees, was captured by Union screw gunboat USS Seneca off Charleston, South Carolina, on 20 November 1862 and was purchased by the Navy from the New York City Prize Court on 9 December 1863.

During October 1864, she operated off Wassaw Sound, Georgia, and returned to Port Royal, South Carolina, in November for repairs.

Thunder serviced blockade vessels off the Savannah River, Georgia, in January and February 1865 and spent most of the remaining months of the war on duty off Tybee Island, South Carolina.
