The Ashley House or "Aunt Polly's House" was a historic house at 3159 Main Street in Fall River, Massachusetts. The house was built circa 1750 in the Steep Brook section of the town, which was then still part of Freetown. It was a 2-1/2 story wood frame structure, five bays wide, with a side-gable roof and clapboard siding. It was one of the only Federal-period with a pedimented doorway that included a half-round fanlight. It was added to the National Register of Historic Places in 1983. The house was dismantled in July 1983. The site is now owned by the New England Power Company.
