USS Martin (1864) was a steamer acquired by the Union Navy during the American Civil War. She was used by the Union Navy for various tasks, including those of a torpedo boat, tugboat, and a picket boat, patrolling Confederate waterways to prevent the South from trading with other countries. Martin, a screw tug built at Albany, New York, in 1864 was purchased by the Navy as James McMartin at New York City 16 June 1864; renamed Martin that same day; and commissioned later in the month, Acting Ens. Rudolph S. Sommers in command.
