The Rappahannock River is a river in eastern Virginia, in the United States,^[2] approximately 195 miles (314 km) in length.^[3] It traverses the entire northern part of the state, from the Blue Ridge Mountains in the west where it rises, across the Piedmont to the Fall Line, and onward through the coastal plain to flow into the Chesapeake Bay, south of the Potomac River.

An important river in American history, the Rappahannock was long an area of occupation by indigenous peoples. Similarly, during the colonial era, early settlements in the Virginia Colony were formed along the river.

During the American Civil War, due to the river's acting as a barrier to north–south troop movements, it effectively functioned as the boundary of the eastern theater of the war, between the "North" (the Union) and the "South" (the Confederate States of America). It was at the center of a major theater of battle where tens of thousands of troops fought against each other. In this period some 10,000 enslaved African Americans escaped to freedom across the river to Union lines, after the first Battle of Fredericksburg.

The river drains an area of 2,848 square miles (7,380 km²), approximately 6% of Virginia. Much of the watershed is rural and forested. Development in the area has increased since the late 20th century with the southward expansion of the metropolitan Washington, D.C. suburbs.
