Forge Farm is an historic farm at 40 Forge Road in Warwick, Rhode Island. Established in the mid-17th century by the Greene family, it is one of the oldest farms in Rhode Island. It was the birthplace of General Nathanael Greene, a prominent American general in the American Revolutionary War. The core of the main house was built in 1684 by James Greene, son of John Greene, who purchased the land from local Native Americans. It has been extended and altered numerous times in the 18th and 19th centuries. Nathanael Greene was born in this house in 1742, and the farm was owned for many years by Nathanael's brother Christopher, and wife, Deborah (Ward) Greene, daughter of Continental Congress member Samuel Ward.
