The Battle of Fairfield was a cavalry engagement during the Gettysburg Campaign of the American Civil War. It was fought July 3, 1863, near Fairfield, Pennsylvania, concurrently with the Battle of Gettysburg, although it was not a formal part of that battle. While a minor fight by the small number of troops deployed, strategically, the Confederate victory secured the important Hagerstown Road, which Robert E. Lee's Army of Northern Virginia would use on July 5 to return to Maryland and then on to safety in Virginia.
