To the south and east is the Atlantic Ocean and to the north and northeast is New Brunswick, a province of Canada.
The Canadian province of Québec is to the northwest.
Maine is the northernmost state in New England and the largest, accounting for almost half of the region's entire land area.
Maine is the only state to border exactly one other American state (New Hampshire).

Maine is the easternmost state in the United States both in its extreme points and in its geographic center.
The town of Lubec is the easternmost organized settlement in the United States.
Its Quoddy Head Lighthouse is also the closest place in the United States to Africa and Europe.
Estcourt Station is Maine's northernmost point, as well as the northernmost point in New England. (
For more information see extreme points of the United States.)

Maine's Moosehead Lake is the largest lake wholly in New England, since Lake Champlain is located between Vermont, New York and Québec.
A number of other Maine lakes, such as South Twin Lake, are described by Thoreau in The Maine Woods (1864).
Mount Katahdin is the northern terminus of the Appalachian Trail, which extends southerly to Springer Mountain, Georgia, and the southern terminus of the new International Appalachian Trail which, when complete, will run to Belle Isle, Newfoundland and Labrador.

Machias Seal Island and North Rock, off the state's Downeast coast, are claimed by both Canada and the American town of Cutler, and are within one of four areas between the two countries whose sovereignty is still in dispute, but it is the only one of the disputed areas containing land.
Also in this easternmost area in the Bay of Fundy is the Old Sow, the largest tidal whirlpool in the Western Hemisphere.

Maine is the least densely populated U.S. state east of the Mississippi River.
It is called the Pine Tree State; over 80% of its total land is forested or unclaimed, the most forest cover of any U.S. state.
In the wooded areas of the interior lies much uninhabited land, some of which does not have formal political organization into local units (a rarity in New England).
The Northwest Aroostook, Maine unorganized territory in the northern part of the state, for example, has an area of 2,668 square miles (6,910 km²) and a population of 10, or one person for every 267 square miles (690 km²).

Maine is in the temperate broadleaf and mixed forests biome.
The land near the southern and central Atlantic coast is covered by the mixed oaks of the Northeastern coastal forests.
The remainder of the state, including the North Woods, is covered by the New England-Acadian forests.

Maine has almost 230 miles (400 km) of coastline (and 3,500 miles (5,600 km) of tidal coastline).
West Quoddy Head, in Lubec, Maine, is the easternmost point of land in the 48 contiguous states.
Along the famous rock-bound coast of Maine are lighthouses, beaches, fishing villages, and thousands of offshore islands, including the Isles of Shoals which straddle the New Hampshire border.
There are jagged rocks and cliffs and many bays and inlets.
Inland are lakes, rivers, forests, and mountains.
This visual contrast of forested slopes sweeping down to the sea has been summed up by American poet Edna St. Vincent Millay of Rockland and Camden, Maine, in "Renascence":
All I could see from where I stood
Was three long mountains and a wood;
I turned and looked the other way,
And saw three islands in a bay.

Geologists describe this type of landscape as a "drowned coast", where a rising sea level has invaded former land features, creating bays out of valleys and islands out of mountain tops.
A rise in land elevation due to the melting of heavy glacier ice caused a slight rebounding effect of underlying rock; this land rise, however, was not enough to eliminate all the effect of the rising sea level and its invasion of former land features.

Much of Maine's geomorphology was created by extended glacial activity at the end of the last ice age.
Prominent glacial features include Somes Sound and Bubble Rock, both part of Acadia National Park on Mount Desert Island.
