The Scioto River is a river in central and southern Ohio more than 231 miles (372 km) in length. It rises in Hardin County just north of Roundhead, Ohio, flows through Columbus, Ohio, where it collects its largest tributary, the Olentangy River, flows south into Appalachian Ohio, and meets the Ohio River at Portsmouth. Early settlers and Native Americans used the river for shipping, but it is too small for modern commercial craft. The primary economic importance for the river now is for recreation and drinking water. It is the longest river that is entirely within Ohio.

Columbus, the capital city of Ohio, was founded on the east bank of the Scioto River in 1812. The city was founded as its capitol, beside the town of Franklinton, since incorporated into Columbus. The city's early history was gradual, as residents dealt with flooding and cholera epidemics, and the city had few direct connections to other cities. This led creation of a feeder canal, and later, freight and passenger railroads. The city became known for its industry and commercial businesses into the 20th century, though it experienced a lull in development in the late 20th century. In the 21st century, Columbus has been increasingly revitalized, led by parks projects, new developments, and efforts to beautify individual neighborhoods.
