The Buttolph-Williams House is a historic house museum in Wethersfield, Connecticut. Built in 1711, it is one of the oldest surviving houses in the town. The house underwent a careful restoration in 1947, led by architect Frederick C. Palmer, in which much of its original material was preserved. The interior features rare 17th and early 18th century antiques and was the setting for Elizabeth George Speare’s Newbery Medal-winning novel "The Witch of Blackbird Pond" (1958). The property is now owned by Connecticut Landmarks and operated by the nearby Webb-Deane-Stevens Museum. It is open for regular tours between May and October.
