Ohio is bordered by five states (and Lake Erie to the north):
| Direction | State | Border Length | Major Border Features |
|---|---|---|---|
| North | Michigan | ~150 mi | Lake Erie, Toledo Strip (historic dispute) |
| West | Indiana | ~160 mi | Straight line (surveyed), I-70/I-74 corridors |
| South | Kentucky | ~430 mi | Ohio River (entire border) |
| Southeast | West Virginia | ~160 mi | Ohio River (upper), Appalachian foothills |
| East | Pennsylvania | ~160 mi | Straight line (surveyed), Pittsburgh tri-state area |
Ohio's central location and river/lake borders made it a transportation and industrial crossroads—canals, railroads, highways, and now logistics hubs.
