USS Augusta (CA-31) (originally CL-31) was a Northampton-class heavy cruiser of the United States Navy, notable for service in the Atlantic and Mediterranean during World War II, and for her occasional use as a presidential flagship carrying both Franklin D. Roosevelt and Harry S. Truman under wartime conditions (including at the Newfoundland Conference). According to the Dictionary of American Naval Fighting Ships, she is named after Augusta, Georgia (rather than Augusta, Maine), and was sponsored by Miss Evelyn McDaniel of that city.
