The Eight States That Border Tennessee

Tennessee sits at a geographic crossroads, sharing boundaries with eight states—tied with Missouri for the most of any U.S. state. Here's the clockwise lineup from due north:

1. Kentucky – Northern border (defined by the 36°30′ parallel, with the Mississippi River forming the far western tip).
2. Virginia – Northeastern corner (a short, mountainous boundary in the Cumberland Gap area).
3. North Carolina – Eastern border along the Appalachian crest (Great Smoky Mountains).
4. Georgia – Southern border (straight-line survey at 35°N, with a tiny nick near Chattanooga).
5. Alabama – Southwestern border (also 35°N).
6. Mississippi – Western border (Mississippi River forms the boundary).
7. Arkansas – Northwestern border (Mississippi River).
8. Missouri – Northwestern tip (Mississippi River; only ~15 miles of contact via the Kentucky Bend exclave).

Why So Many Neighbors?

Tennessee's elongated east-west shape (440 mi wide × 112 mi tall) and its use of both the Mississippi River and the 35°/36°30′ parallels as borders maximize contact with surrounding states. The result: a state where you can stand in Bristol and be in Virginia, drive two hours to Memphis and gaze across the river at Arkansas, and hit Kentucky, Missouri, and Mississippi all in one long day.
