USS Mullany (DD-325) was a Clemson-class destroyer built for the United States Navy during World War I.

The turbines were designed to produce a total of 27,000 shaft horsepower (20,000 kW) intended to reach a speed of 35 knots (65 km/h; 40 mph).

The ships carried a maximum of 371 long tons (377 t) of fuel oil which was intended gave them a range of 2,500 nautical miles (4,600 km; 2,900 mi) at 20 knots (37 km/h; 23 mph).

[4] Mullany named for James Robert Madison Mullany, was laid down 3 June 1919 by Bethlehem Shipbuilding Corporation, San Francisco, California; launched 9 July 1920; sponsored by Miss Alice Lee Hall; and commissioned at Mare Island Navy Yard 29 March 1921.

Based at San Diego, California, Mullany operated along the west coast through most of her career, sailing annually to the Panama Canal Zone and the Caribbean for combined fleet maneuvers.
