USS Smartt (DE-257) was an Evarts-class destroyer escort of the United States Navy during World War II.

She took part in operations in the Atlantic Ocean to protect convoys and other ships from German submarines and fighter aircraft.

He was assigned to Patrol Squadron 11 at Naval Air Station, Kaneohe Bay, Oahu, Hawaii and was killed in action on 7 December 1941 during the Japanese Attack on Pearl Harbor.

Smartt fitted out at Boston and sailed on 6 July to Bermuda, B.W.L., for her shakedown cruise which lasted until 7 August when she returned for yard availability.

Between 4 July 1944 and 14 June 1945, Smartt made six convoy escort voyages from the United States to the Mediterranean and return.

The escort moved to Casco Bay, Maine, and conducted local operations there from 18 July to 10 September when she returned to New York for inactivation.
