Maine ( ) is the easternmost state in the New England region of the Northeastern United States. It borders New Hampshire to the west, the Gulf of Maine to the southeast, and the Canadian provinces of New Brunswick and Quebec to the northeast and northwest, respectively. Although Maine is the largest state in New England by total area, it is also the 12th-smallest by area, the 9th-least populous, the 13th-least densely populated, and the most rural of the 50 U.S. states. Maine's capital is Augusta, and its most populous city is Portland.

Maine has traditionally been known for its jagged, rocky Atlantic Ocean and bayshore coastlines; smoothly contoured mountains; heavily forested interior; picturesque waterways; and its wild lowbush blueberries and seafood cuisine, especially lobster and clams. Coastal and Down East Maine have emerged as important centers for the creative economy, especially in the vicinity of Portland, which is also bringing gentrification.
