The Jonah Warren House is a historic house at 64 Warren Street in Westborough, Massachusetts. Estimated to have been built in the 1720s, this 2.5 story wood frame house is one of the oldest buildings in Westborough. It was built along what was known as the Old Connecticut Path, a former Native American trail. Jonah Warren, the owner and probable builder, moved to the Westborough area (then part of Marlborough) in 1719. A tanner by trade, he also helped to build the first meetinghouse in Westborough.
