US states by landlocked status

States are landlocked if they touch no coastlines, but if they touch only landlocked states, they are doubly landlocked. If touching only doubly landlocked states they are triply landlocked, and so on.

If we’re not counting the Great Lakes, Minnesota is the most landlocked state, being quadruply landlocked. You’d have to cross at least 4 states in any route you took to the ocean.

If we’re counting the Great Lakes as coastline, there’s only doubly landlocked states.

Worldwide, there are 44 landlocked countries, but only Uzbekistan and Liechtenstein are doubly landlocked.
