USS Allagash (AO-97) was an Cimarron-class oiler constructed for the U.S. Navy for use in World War II. She had the dangerous task of supplying fuel and ammunition to ships in and near combat area. Allagash was laid down on 26 October 1944 at Sparrows Point, Maryland, by the Bethlehem Steel Co. under a Maritime Commission contract (MC hull 2559); launched on 14 April 1945; sponsored by Mrs. Reuben D. Vining; acquired by the Navy on a loan-charter basis on 21 August 1945; and commissioned that same day.
