what is the only us state that does not border another state

The only U.S. state that does not border any other U.S. state is Hawaii.

Quick scoop

• Hawaii is an island chain in the central Pacific Ocean, located far from the North American mainland, so it shares no land borders with any other U.S. state.

• By contrast, Alaska does not touch the other 48 contiguous states, but it still borders Canada, so it is not counted as a state with no borders at all, only as non‑contiguous.

• All other U.S. states either share land borders with at least one neighbor or, in Maine’s case, exactly one other state (New Hampshire). Hawaii is the only one with no state borders.
