Ironstone is an historic village, (today known mainly as South Uxbridge), in the township of Uxbridge, Massachusetts, United States. It derived its name from plentiful bog iron found here which helped Uxbridge to become a center for three iron forges in the town's earliest settlement. South Uxbridge has historic sites, picturesque weddings, hospitality, industrial and distribution centers, and the new Uxbridge High School. This community borders North Smithfield, and Burrillville, Rhode Island, and Millville, Massachusetts. South Uxbridge receives municipal services from Uxbridge, for fire, police, EMS, School district, public works, and other services. There is a South Uxbridge fire station of the Uxbridge fire department. Worcester's Judicial District includes Uxbridge District Court. Ironstone appears on the Blackstone U.S. Geological Survey Map.
