The Dr. Moses Mason House is a historic house museum at the northeast corner of Broad Street and Mason Street in Bethel, Maine. Built c. 1813-15, it is notable as the home of one of Bethel's early doctors and first postmaster, Moses Mason (1789-1866), and for the murals drawn on some of its walls by the itinerant artist (among other professions he engaged) Rufus Porter. The building was listed on the National Register of Historic Places in 1972; it is now owned by the Bethel Historical Society, and is open year-round for tours (by appointment only in the colder months).
