What Borders Maine? (Hint: Not What You Think)

Maine shares land borders with only one U.S. state: New Hampshire to the west.

Its northern and eastern boundaries are international: the Canadian provinces of Quebec (northwest/north) and New Brunswick (northeast/east). The Atlantic Ocean defines its southern coastline.

This unique geography makes Maine the only U.S. state bordering exactly one other state—and the easternmost state in the contiguous U.S.
