is one of two downeast coastal counties located east of the Penobscot River. It was formed when the extensive Lincoln County was divided on June 25, 1789 by adding Hancock and Washington counties. The westerly portion of the new Hancock County was eventually split off to form Waldo County. See an 1860 map of the county in the Map Cabinet.
The county includes several major islands (Deer Isle, Swans Island, and Mount Desert Island) and Acadia National Park.
Currently the county consists of the following: towns of Amherst, Aurora, Bar Harbor, Blue Hill, Brooklin, Brooksville, Bucksport, Castine, Cranberry Isles, Dedham, Deer Isle, Eastbrook, Ellsworth, Franklin, Frenchboro, Gouldsboro, Great Pond, Hancock, Lamoine, Mariaville, Mount Desert, Orland, Osborn, Otis, Penobscot, Sedgwick, Sorrento, Southwest Harbor, Stonington, Sullivan, Surry, Swans Island, Tremont, Trenton, Verona Island, Waltham and Winter Harbor; and several unorganized townships.
Castine was the first county seat until 1838 when the shire town was moved to the City of Ellsworth, which now hosts the county government, courthouse, and the county jail.
In 2010, Hancock County was Maine’s eighth largest county by population at 4.3% of the state’s total, with a census count of 54,418, a 5.1% increase over 2000.
