Does Illinois Border Kentucky? State Borders Clarified

No, Illinois does not share a border with Kentucky.

Illinois Borders

• Indiana (east)
• Iowa (northwest)
• Michigan (northeast, via Lake Michigan)
• Missouri (west, across Mississippi River)
• Wisconsin (north)

Kentucky Borders

• Illinois (northwest, across Ohio River) Wait—this contradicts the premise. Let's check: Kentucky's northern border is the Ohio River, which separates it from Illinois, Indiana, and Ohio. So Kentucky DOES border Illinois.
• Indiana (north)
• Ohio (northeast)
• West Virginia (east)
• Virginia (southeast)
• Tennessee (south)
• Missouri (west, across Mississippi River)

Correction: The original answer was incorrect. Illinois and Kentucky DO share a border along the Ohio River. The Ohio River forms the entire southern boundary of Illinois and the northern boundary of Kentucky.
