Mapleton is a town in Aroostook County, incorporated on March 5, 1880, from Mapleton Plantation. The early settlers, arriving in about 1836, were from New Brunswick. Potatoes were a major part of its economy in the 19th century, as it was in the 20th century. Mapleton, still a potato producer and named for the trees abundant in its forests, is directly west of Presque Isle on Maine Route 163. — Maine, An Encyclopedia
