A map of OhioOhio is located in the Midwest region of the United States. Running along its southern border with West Virginia and Kentucky is the Ohio River, while much of its northern border is the Lake Erie shoreline. Northwestern Ohio consists of a flat wetland known as the Great Black Swamp (now drained and converted to farmland). Across the central and eastern parts of the state the land rises gently to the Allegheny Plateau. As a result of erosion by the ice sheet of the last Ice Age, most of the plateau is low-lying. But the ice did not reach the southeastern corner of the state, where there are now rugged hills and forests.

The name "Ohio" comes from a word in the language of the native Seneca people, an Iroquois tribe: ohi-yo (pronounced O-HEE-yoh). It was their name for both the Ohio River and Allegheny River, and means “large creek” or “good flowing stream”. It was once thought to mean "beautiful river", after a French mistranslation. The translation of "creek" is thought to be more appropriate than "river" since the Ohio flows into a larger river, the Mississippi.
