From there, it flows southwestward for approximately 981 miles (1,579 km), ultimately emptying into the Mississippi River at Cairo, Illinois. This extensive journey takes it through a total of five states:

Pennsylvania: The river's birth place, Pennsylvania only briefly holds the Ohio River before it crosses into Ohio. This section, although short, is historically significant, as Pittsburgh's location at the river's headwaters played a critical role in westward expansion.
Ohio: The state of Ohio lends its name to the river, and it forms a significant portion of the river's course. The Ohio River significantly shapes Ohio's geography and history, impacting transportation, industry, and settlement patterns throughout the state. Major cities along this stretch include Cincinnati and Portsmouth.
West Virginia: West Virginia's borders are heavily influenced by the Ohio River. A large section of the state's western border is formed by the river, influencing its development and trade routes. The river's presence has shaped the state's economy and influenced its cultural identity.
Kentucky: Kentucky shares a lengthy border with the Ohio River, impacting transportation, commerce, and the growth of its major cities, including Louisville and Paducah. The river's influence on Kentucky's development is profound, contributing to its agricultural and industrial heritage.
Indiana: Indiana's southern border is defined by the Ohio River. While not as extensively impacted as Kentucky or Ohio, the river significantly shaped the development of southern Indiana's communities and infrastructure. The river’s influence extends to its trade routes and economic activities. Cities like Evansville are prime examples.
Illinois: The Ohio River's journey concludes at its confluence with the Mississippi River in Cairo, Illinois. This point marks a significant geographical marker, signifying the joining of two powerful river systems that shaped the development of the American Midwest.
