What States Does the Ohio River Run Through?
The Ohio River runs through or along the border of six states:
- West Virginia
The river starts where the Allegheny and Monongahela Rivers meet, and that point is in Pittsburgh, Pennsylvania.
Where Does the Ohio River Start and End?
The Ohio River begins in Pittsburgh, Pennsylvania, and stretches for 981 miles until it ends at Cairo, Illinois. This is where the Ohio River drains into the Mississippi.
One of the most interesting things to know about the Ohio River is that it’s the largest tributary of the Mississippi River in the United States. Of course, this ranking is based on volume.
Which State Has the Legal Ownership of the Ohio River?
Out of the six states that the river runs through, Kentucky has ownership of the Ohio River.
It goes without saying that the other states have claimed ownership of different stretches of the river since the late 1700s.
Of course, that was all because the Ohio River was a major trade route. Yet, in 1792, the government decided that it was Kentucky that owned the Ohio River along the state’s border with Ohio, Illinois, and Indiana.
The reason behind this decision is that this boundary was the low point of the river’s northernmost bank.
About two centuries later, the State of Ohio sought to gain the claim to the Ohio River a second time. In 1966, the state made a point that the course of the river had fluctuated since 1792, making the aforementioned low point near the south bank of the river today.
However, the United States Supreme Court didn’t change the legal ownership of the Ohio River, so it still belongs to Kentucky until this day.

Because the Ohio was a strategic waterway for trading and transportation, it was a key factor in the struggle between the French and the English in the 1750s.
