The Palmer-Marsh House is a historic house in Bath, North Carolina. It was built around the year 1744 most probably by Michael Coutanche. The structure is believed to be one of the oldest surviving dwelling structures in the state of North Carolina.

The Palmer-Marsh House is best noted for being the home of Colonel Robert Palmer, the Surveyor General of NC from 1753 to 1771 and Collector of Customs for the Port of Bath. Governor William Tryon also visited the residence in 1764. The property stayed in the Palmer family until the 1780s, after Colonel Palmer left for England in 1771 and his son took residence on the house. The Marsh family acquired the house in the 19th century. They were prominent for their businesses.

Designated a National Historic Landmark in 1970, the Palmer-Marsh House is open for tours.
