USS Bluebird (AM-72) was an Albatross-class minesweeper acquired by the U.S. Navy during World War II for clearing minefields during fleet operations.
M/V Maine—a steel-hulled fishing trawler constructed in 1931 at Bath, Maine, by Bath Iron Works—was purchased by the Navy on 13 August 1940 from the Booth Fisheries Co., Boston, Massachusetts; renamed Bluebird and designated a minesweeper, AM-72, on 14 August 1940; converted to naval service at Boston, Massachusetts, by the General Ship & Engineering Works; and commissioned at the Boston Navy Yard on 22 November 1940.
