The Army of Northern Virginia was the primary military force of the Confederate States of America in the Eastern Theater of the American Civil War. It was also the primary command structure of the Department of Northern Virginia. It was most often arrayed against the Union Army of the Potomac.

The name Army of Northern Virginia referred to its primary area of operation, as did most Confederate States Army names. The Army originated as the (Confederate) Army of the Potomac, which was organized on June 20, 1861, from all operational forces in northern Virginia. On July 20 and July 21, the Army of the Shenandoah and forces from the District of Harpers Ferry were added. Units from the Army of the Northwest were merged into the Army of the Potomac between March 14 and May 17, 1862. The Army of the Potomac was renamed Army of Northern Virginia on March 14. The Army of the Peninsula was merged into it on April 12, 1862.

Robert E. Lee's biographer, Douglas S. Freeman, asserts that the army received its final name from Lee when he issued orders assuming command on June 1, 1862. However, Freeman does admit that Lee corresponded with Joseph E. Johnston, his predecessor in army command, prior to that date and referred to Johnston's command as the Army of Northern Virginia. Part of the confusion results from the fact that Johnston commanded the Department of Northern Virginia (as of October 22, 1861) and the name Army of Northern Virginia can be seen as an informal consequence of its parent department's name. Jefferson Davis and Johnston did not adopt the name, but it is clear that the organization of units as of March 14 was the same organization that Lee received on June 1, and thus it is generally referred to today as the Army of Northern Virginia, even if that is correct only in retrospect.
