The Bethlehem-Fairfield Shipyard of Baltimore, Maryland, was a shipyard in the United States from 1941 until 1945. Located on the south shore of the Middle Branch of the Patapsco River which serves as the Baltimore Harbor, it was owned by the Bethlehem Shipbuilding Company, created by the Bethlehem Steel Corporation of Bethlehem, Pennsylvania, which had operated a major waterfront steel mill outside Baltimore to the southeast at Sparrows Point, Maryland in rural Baltimore County since the 1880s.
