The Bridgewater Iron Works is a historic industrial site located on High Street in Bridgewater, Massachusetts, United States, along the banks of the Town River. Previously known as Lazell, Perkins and Company, by the mid-19th century, the Bridgewater Iron Manufacturing Company was one of the largest iron works in the United States, specializing in heavy castings and forgings. The property was later acquired by the Stanley Works, with the surrounding village still known to this day as Stanley.
