The Moore-Mayo House is a historic house on Lighthouse Road in Bass Harbor, a village of Tremont, Maine. The architecturally vernacular house was built beginning in 1947 by the authors Ruth Moore and Eleanor Mayo, who lived and wrote there until their respective deaths in 1989 and 1981. Moore in particular has been cited as a major mid-20th century writer of Maine culture. The house was listed on the National Register of Historic Places in 2004.
