USS Shawmut was a 593-ton steamer acquired by the U.S. Navy and put to use by the Union during the American Civil War.

Shawmut served the Union Navy primarily as a gunboat with howitzers for bombardment, and various other rifles and cannon for use at sea in apprehending blockade runners attempting to "run" the Union blockade of the Confederate States of America.
