State-Wise Breakdown of the Ohio River
While the Ohio River is famous for forming the Ohio River Valley, it does not pass equally through all six states — most of its length forms a border rather than running through the interior of a state.
| State | Role of the River |
|---|---|
| Pennsylvania | Source of the river (Pittsburgh); flows for a short stretch before reaching the Ohio–West Virginia border. |
| Ohio | Forms the entire northern border of the river, separating Ohio from West Virginia and Kentucky |
| West Virginia | Forms the state’s western border, separating it from Ohio |
| Kentucky | Forms the entire northern border, separating Kentucky from Ohio, Indiana, and Illinois |
| Indiana | Forms the southern border, separating Indiana from Kentucky |
| Illinois | The river’s final stretch, ending at the confluence with the Mississippi River near Cairo |
