The Thresher Mill is a historic industrial facility on West Barnet Road in Barnet, Vermont. First developed in 1836, it was the last water-powered mill to operate on the Stevens River, lasting into the late 20th century. The property, which includes an original mill dam and a surviving 1872 mill building, as well as archaeological sites of other industrial buildings, was listed on the National Register of Historic Places in 1996. It is now styled Ben's Mill, and is a local museum.
