{{Short description|States in the U.S. that border either Canada, Mexico, Cuba, or Russia}}400px|thumb|International border states are shown in red on this map. Florida shares a water border with Cuba and The Bahamas.|alt=The '''international border states''' are those states in the U.S. that border either the Bahamas, Canada, Cuba, Mexico, or Russia. With a total of eighteen of such states, thirteen (including Alaska) lie on the U.S.–Canada border, four lie on the U.S.–Mexico border, and one has maritime borders with Cuba and The Bahamas.

== Border with Canada == {{Main|Northern Tier (United States)}} Thirteen states lie on the U.S.–Canada border. The U.S. states of Indiana, Illinois, and Wisconsin do not share a direct geographic border with Canada. They do, however, possess customs facilities because they border the Great Lakes, on which international commerce comes from Canada. (All three states border Lake Michigan, while Wisconsin also borders Lake Superior.)
