Maine is a state in the New England region of the United States, and the northeasternmost state in the contiguous 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, and shares a maritime border with Nova Scotia. It is the only state to border only one other state, which is New Hampshire.

As of 2024, Maine's population stood at a Census-estimated 1,400,000, the state's highest-ever population estimate. Maine's capital is Augusta, while its most populous city is Portland.
