States Bordering Missouri: All Eight Neighbors
Missouri's Eight Bordering States
Missouri sits at the crossroads of the Midwest and South, sharing boundaries with eight states:
- Iowa – north
- Illinois – northeast (across the Mississippi River)
- Kentucky – east (across the Mississippi River)
- Tennessee – southeast (small border via Mississippi River)
- Arkansas – south
- Oklahoma – southwest
- Kansas – west
- Nebraska – northwest
Only Tennessee and Oklahoma touch Missouri at relatively short segments; the others share extensive borders. The Mississippi River forms much of the eastern boundary.
