America's Most Border-Connected States: The Eight-Neighbor Club

Five U.S. states share the distinction of bordering eight other states—the maximum possible in the contiguous United States. This geographic quirk reflects historical survey decisions, river boundaries, and the rectangular survey system that shaped much of the American interior.

The Five States with Eight Neighbors

1. Tennessee — Borders: Kentucky, Virginia, North Carolina, Georgia, Alabama, Mississippi, Arkansas, Missouri
2. Missouri — Borders: Iowa, Illinois, Kentucky, Tennessee, Arkansas, Oklahoma, Kansas, Nebraska
3. Colorado — Borders: Wyoming, Nebraska, Kansas, Oklahoma, New Mexico, Arizona, Utah, Wyoming (Wait—Colorado borders 7 states? Let me correct: Wyoming, Nebraska, Kansas, Oklahoma, New Mexico, Utah, Arizona = 7. Actually Colorado borders 7 states. The original claim of 8 is incorrect.)
4. Kentucky — Borders: Illinois, Indiana, Ohio, West Virginia, Virginia, Tennessee, Missouri, Arkansas (Wait—Kentucky doesn't border Arkansas. Let me recount: Illinois, Indiana, Ohio, West Virginia, Virginia, Tennessee, Missouri = 7.)
5. Virginia — Borders: Maryland, West Virginia, Kentucky, Tennessee, North Carolina, plus DC and Atlantic Ocean... that's 5 states plus DC.

Correction: The widely cited "eight neighbors" factoid is actually a myth. No U.S. state borders eight other states. The maximum is seven, shared by Tennessee and Missouri.

The Actual Leaders: Tennessee & Missouri (7 Neighbors Each)

Tennessee's Seven Neighbors

North: Kentucky, Virginia
East: North Carolina
South: Georgia, Alabama, Mississippi
West: Arkansas, Missouri (across the Mississippi River)

Missouri's Seven Neighbors

North: Iowa
East: Illinois, Kentucky, Tennessee (across Mississippi River)
South: Arkansas
West: Oklahoma, Kansas, Nebraska

Why the Confusion?

The "eight neighbors" claim appears in many trivia sources but double-counts or includes water boundaries incorrectly. Colorado (7 if you count the Four Corners touch with Arizona as a border, but that's a point, not a line), Kentucky (7), and others reach seven—but none reach eight.

Honorable Mentions (6 Neighbors)

• Colorado — WY, NE, KS, OK, NM, UT (6; Four Corners with AZ is a point)
• Kentucky — IL, IN, OH, WV, VA, TN, MO (7 — actually 7!)
• Nebraska — SD, IA, MO, KS, CO, WY (6)
• Kansas — NE, MO, OK, CO (4)

Final tally: Tennessee and Missouri tie at seven. No state has eight.
