The First Corps, Army of Northern Virginia (or Longstreet's Corps) was a military unit fighting for the Confederate States of America in the American Civil War. It was formed in early 1861 and served until the spring of 1865, mostly in the Eastern Theater. The corps was commanded by James Longstreet for most of its existence.

In part or as a whole, the corps fought in nearly all of the major battles in the Eastern Theater, such as Fredericksburg, Gettysburg, The Wilderness, Cold Harbor, and the Siege of Petersburg. The corps also fought in Tennessee and performed important forage service in Suffolk, Virginia. It was disbanded shortly following Gen. Robert E. Lee's surrender to Union forces on April 9, 1865.
