The Third Battle of Winchester (or Battle of Opequon), was fought just outside Winchester, Virginia, on September 19, 1864, during the Valley Campaigns of 1864 in the American Civil War.

Because of its size, intensity, serious casualties on both sides (particularly among the general officers) and its result (Confederates never again controlling Winchester and President Abraham Lincoln winning re-election), many historians consider this the most important conflict of the Shenandoah Valley.
