Rapidan River

The Rapidan River is a tributary of the Rappahannock River in northern Virginia, United States. It originates in the Blue Ridge Mountains in Shenandoah National Park and flows generally eastward through the Piedmont region. The river is approximately 88 miles (142 km) long.

The Rapidan's name is believed to be derived from a Native American word, possibly "Rapid Ann," referring to its fast-flowing waters where it descends from the mountains.

The river is significant for its role in the American Civil War. The Rapidan River served as a major strategic boundary between the Union Army of the Potomac and the Confederate Army of Northern Virginia, particularly during the campaigns of 1862-1864. Numerous battles and encampments occurred along its banks, including the Battle of the Wilderness and the Battle of Spotsylvania Court House.

The Rapidan River is now a popular destination for recreational activities, including fishing, canoeing, and hiking. It is also a source of drinking water for several communities in the region. The river's watershed is managed to protect its water quality and ecological health.
