Wilsondale Farm is a dairy farm in Gray, Maine, United States. It is notable for its introduction of a specific breed of Holstein cow. The farm, of 900 acres (3,600,000 m2), was purchased by New Gloucester's Pineland Farms in 2001. It is run by the Wilson family, as it has been since 1961. The street on which the farm stands, Bull Run, is so named because of the bulls that George T. Merrill and his son, George E., used to have at the farm. As of 2011, the farm had thirty cows.
