Jackson's Valley campaign, also known as the Shenandoah Valley campaign of 1862, was Confederate Maj. Gen. Thomas J. "Stonewall" Jackson's spring 1862 campaign through the Shenandoah Valley in Virginia during the American Civil War. Employing audacity and rapid, unpredictable movements on interior lines, Jackson's 17,000 men marched 646 miles (1,040 km) in 48 days and won several minor battles as they successfully engaged three Union armies (52,000 men), preventing them from reinforcing the Union offensive against Richmond.

Jackson followed up his successful campaign by forced marches to join Gen. Robert E. Lee for the Seven Days Battles outside Richmond. His audacious campaign elevated him to the position of the most famous general in the Confederacy (until this reputation was later supplanted by Lee) and has been studied ever since by military organizations around the world.
