USS Rail (AM-26/AT-139/ATO-139) was a Lapwing-class minesweeper built for the United States Navy during World War I. She was the first U.S. Navy ship named for the rail, a small wading bird, related to the cranes. Rail, a single-screw, steel "bird"-class minesweeper, was laid down on 15 December 1917 by the Puget Sound Navy Yard, Bremerton, Washington; launched 25 April 1918; sponsored by Mrs. Robert Morgan; and commissioned on 5 June 1918.
