Which U.S. State Is The Only State To Share A Border With A Single Neighboring State?
The majority of U.S. states are nestled in with other states, and even if they enjoy an expansive coastline (like California), they still rub shoulders with landlocked neighbors; then of course there are the states that share no borders at all with other states (island state Hawaii and far-north state Alaska with only a single international boundary with Canada).
The unique distinction of only bordering a single state, however, belongs to Maine. Located far up the East coast of the United States, Maine shares a single state border with New Hampshire. The rest of Maine’s borders are shared with the Canadian provinces of Quebec and New Brunswick, as well as the Atlantic Ocean.
