Stanton's Mill is a historic grist mill complex located at Grantsville, Garrett County, Maryland, consisting of five interrelated buildings and structures. The Stanton's Mill building dates from about 1797. It is two stories and constructed of heavy timber frame with a gable roof; an addition was constructed in 1890. The complex includes a stone-faced, mid-19th-century timber crib dam and raceway, natural earthen tailrace, and a small, single-span stone arch bridge, dating to 1813, constructed as part of the National Road. Also on the property is a frame storage building, constructed about 1900.
