Smiling Hill Farm is a 500 acre traditional New England farm encompassing parts of the municipalities of Westbrook, Scarborough, and Gorham, Maine. Founded in 1720 as the homestead of Nathaniel Knight, the 12th-generation descendants continue to operate the farm today. Known as the "Knight Farm", the farm was renamed "Smiling Hill Farm" by Roger D. Knight in 1974. Roger named the farm after a favorite childhood book, "Smiling Hill Farm" by Miriam E. Mason (1937). Smiling Hill Farm is known for its characteristic smiling cow logo. According to Family Business magazine, Smiling Hill Farm is the 9th oldest continually operating family business in the United States.
