The Harriman School is a historic one-room schoolhouse on North Road in rural Sebec, Maine. Built in 1860, it is the oldest of two surviving 19th-century district schoolhouses in the community. The vernacular Greek Revival building served as a public school until 1933, and was converted into a museum by the Sebec Historical Society after it acquired the property in 1966. The building was listed on the National Register of Historic Places in 1996.
