The James River in the Commonwealth of Virginia in the United States is 348 miles (560 km) long and drains a watershed of 10,432 square miles (27,020 km2) with a population of 2.8 million people. It is the 12th longest river in the United States that remains entirely within a single state. The James begins in the Appalachian Mountains and flows into the Chesapeake Bay at Hampton Roads. From there, its waters enter the Atlantic Ocean a few miles further east. Tidal waters extend west from the Bay to Richmond, the capital of Virginia.
