Formed on April 1, 1816 from the northern part of what was then Hancock County, it later gave up territory to form Piscataquis and Aroostook counties. As with many counties, towns and borders changed throughout the early 19th century. See an 1859 map of the county in the Map Cabinet.
The county currently consists of the cities of Bangor, Brewer, Old Town; and towns of Alton, Bradford, Bradley, Burlington, Carmel, Charleston, Chester, Clifton, Corinna, Corinth, Dexter, Dixmont, East Millinocket, Eddington, Edinburg, Enfield, Etna, Exeter, Garland, Glenburn, Greenbush, Hampden, Hermon, Holden, Howland, Hudson, Kenduskeag, Lagrange, Lakeville, Lee, Levant, Lincoln, Lowell, Mattawamkeag, Maxfield, Medway, Milford, Millinocket, Mount Chase, Newburgh, Newport, Orono, Orrington, Passadumkeag, Patten, Plymouth, Springfield, Stacyville, Stetson, Veazie, Winn, Woodville; the plantations of Carroll, Drew, Seboeis, and Webster; townships including Argyle, Greenfield, Kingman, Mattamiscontis, among others; and the Penobscot Nation reservation on Indian Island in the Penobscot River.
