Introduction:
Maine uses counties with county seats. Our detailed map foregrounds counties and seats; thin corridor lines for interstates and U.S. routes appear only to orient the reader. That makes it a best map format for research, schoolwork, and planning.
This Map of Maine is a detailed map that spotlights every county boundary, each county seat, and the coastal and international borders that define the state. As a Maine map with cities, counties and roads network, it uses restrained road styling so counties and seats stay readable while you still see how places line up along the I-95 spine, the US-1 coast route, US-2 across the interior, US-201 up the Kennebec, and US-302 toward New Hampshire. Rivers, bays, and large lakes are labeled to fix each county in its landscape: St. John River, St. Croix River, Penobscot River, Kennebec River, Androscoggin River, Moosehead Lake, Sebago Lake, Rangeley Lakes, Gulf of Maine.
Maine’s east and north meet Canada. The long north edge touches the province of New Brunswick along the St. John and the east edge touches it again along the St. Croix to Passamaquoddy Bay. The northwest corners meet Québec through high forest and lakes. The entire south and east face the Gulf of Maine and the Atlantic Ocean. The road-light lines show border crossings at Houlton, Fort Kent, Madawaska, Van Buren, Calais, and Vanceboro without drowning the county names.
The northern third of the page is Aroostook County, the largest in Maine. The map marks Houlton on the I-95 corridor at the east gate and shows Caribou, Presque Isle, Fort Kent, Madawaska, and Van Buren along the St. John valley. The official county seat is Houlton, with a second courthouse in Caribou for the northern registry. Potato fields, timberlands, and river towns define the region. The road-light layout uses I-95 to cue the southern approach and a thin US-1 line up the valley so you can place each town in order.
Follow the border south and you enter Washington County, seat Machias, with Calais and Eastport labeled near Passamaquoddy Bay. The St. Croix River is drawn as the international boundary; light US-1 cues trace the rocky coast through Lubec, Machias, and down toward Milbridge. West of Washington is Hancock County, seat Ellsworth, anchoring Mount Desert Island and Bar Harbor. The map shows the island outline, Frenchman Bay, and the island’s connection to the mainland by the thin ME-3 style line so you can see how Ellsworth funnels traffic to Bar Harbor without the map turning into a driving sheet.
Penobscot County lies inland with the county seat and regional hub Bangor boldly labeled. Brewer, Orono, and Old Town appear along the Penobscot River, and the thin I-95 cue helps you track Bangor northward toward Lincoln and the mill towns. West of Bangor, Piscataquis County is shown in a broad pastel with seat Dover-Foxcroft and the large shape of Moosehead Lake near Greenville. The road styling stays soft; you can still follow the rough arc of US-2 as it crosses from Bangor into Somerset and on toward New Hampshire.
To the west are the high counties that touch Québec. Somerset County lists Skowhegan as the seat; US-201 is shown lightly up the Kennebec River valley toward Jackman and the border. Franklin County centers on Farmington with the Rangeley Lakes labeled near the Canadian line. Oxford County shows Paris (South Paris) as seat, with Norway, Rumford, and Fryeburg marked along the Saco and Androscoggin systems. Those gentle corridor hints let you place mountain passes like US-2 and US-302 without shifting attention away from counties.
At Maine’s center, Kennebec County highlights Augusta, the state capital and county seat on the Kennebec River, with Waterville, Gardiner, Hallowell, and Winthrop nearby. East of Augusta the map shades Waldo County, seat Belfast, on Penobscot Bay, and just south the small wedge of Knox County appears with seat Rockland and the harbor towns Camden and Thomaston. The peninsulas to the southwest are Lincoln County with seat Wiscasset and towns Damariscotta and Boothbay Harbor. The Androscoggin valley displays Androscoggin County, twin cities Auburn (seat) and Lewiston, with Lisbon labeled downriver.
The lower left of the page holds the state’s busiest coastline. Cumberland County shows seat Portland with South Portland, Westbrook, Falmouth, Yarmouth, Brunswick, Cape Elizabeth, Scarborough, and the broad blue shape of Sebago Lake inland. A thin I-295 cue loops around the city; I-95 continues north–south as a light spine so you see how Portland connects to Augusta and Kittery. East across the Kennebec, Sagadahoc County marks Bath as seat with Topsham at the Androscoggin junction. Finally York County anchors the New Hampshire line with seat Alfred and coastal cities Kittery, York, Wells, Ogunquit, Kennebunk, Biddeford, and Saco. The Piscataqua River forms the state line; the road-light treatment of I-95 at Kittery signals Maine’s southern gateway.
Students and travelers use the county blocks to memorize the coastline in order. From the New Hampshire line north and east: York holds Kittery and the long beaches; Cumberland holds Portland, Cape Elizabeth, and Casco Bay; Sagadahoc holds Bath and the Kennebec mouth; Lincoln holds peninsulas like Boothbay and Damariscotta; Knox holds Rockland and Camden; Waldo holds Belfast on the upper bay; Hancock holds Ellsworth and Bar Harbor with the island national park; Washington carries Downeast villages to Calais and the Canadian line. The map’s calm palette keeps that sequence clear.
Residents see in one glance which county a given town belongs to and the location of the county courthouse for documents or juries.
Travelers plan coastal loops or inland drives using counties as day-trip regions while the light highway cues give bearings: I-95 for the north run to Aroostook, US-1 for the coast, US-2 for a cross-state interior line, US-201 for the Kennebec wilderness, US-302 to North Conway.
Geography students learn regional groupings like Aroostook and the St. John Valley, Downeast, Midcoast, Capital Area, Western Mountains, and Greater Portland, with rivers and bays labeled to anchor memory.
Use this as a quick index while viewing the map. Each entry lists the county, county seat, and the key cities, towns, waters, or corridor cues that appear on the artwork.

A road-light county map lets rivers do the heavy lifting. Students follow the Androscoggin from Bethel through Rumford and Lewiston–Auburn to Topsham–Brunswick. They follow the Kennebec from Skowhegan to Augusta, Gardiner, Bath, and the sea. They track the Penobscot from Millinocket and Lincoln to Bangor and Bucksport at the bay. With counties highlighted, those waters define regional groupings better than thick lines ever could.
