Hagerstown Valley is located in Maryland in the United States. It is part of the Great Appalachian Valley, which continues northward as Cumberland Valley in Pennsylvania, and southward as Shenandoah Valley in West Virginia and Virginia. Hagerstown Valley is bounded on the east by South Mountain, part of the Blue Ridge Mountains. On the west the valley is bounded by the Bear Pond Mountains — a range of mountains linking Blue Mountain and North Mountain. The valley is bounded on the south by the Potomac River and on the north by the drainage divide between Conococheague Creek, which flows south to the Potomac River, and Conodoguinet Creek, which flows northeast to the Susquehanna River. Sometimes the boundary between Hagerstown Valley and Cumberland Valley is defined politically, as the state line between Maryland and Pennsylvania. The political definition restricts Hagerstown Valley to Washington County, Maryland, while the larger definition includes part of Franklin County, Pennsylvania as well. Sometimes Cumberland Valley is defined so as to include Hagerstown Valley entirely, extending south all the way to the Potomac River. Antietam Creek flows through Hagerstown Valley to the Potomac River. Antietam National Battlefield is also in the valley, where the Battle of Antietam was fought during the American Civil War. The main cities are Hagerstown, Maryland and Waynesboro, Pennsylvania. The water divide between Hagerstown and Cumberland valleys occurs near the city of Chambersburg, Pennsylvania.

The Battle of Shepherdstown, also known as the Battle of Boteler's Ford, took place September 19–20, 1862, at Boteler's Ford along the Potomac River, during the Maryland campaign of the American Civil War. After the Battle of Antietam on September 17, General Robert E. Lee and the Confederate Army of Northern Virginia withdrew across the Potomac. Lee left a rear guard commanded by Brigadier General William N. Pendleton at Boteler's Ford. On September 19, elements of the Union V Corps dueled with Pendleton's artillery before pushing a short distance across the river at dusk. Pendleton inaccurately informed Lee that all of the artillery of the rear guard had been captured. On the morning of September 20, the Confederates counterattacked with A. P. Hill's Light Division, forcing the Union units back across the Potomac. One Union unit, the 118th Pennsylvania Infantry Regiment, did not withdraw at the same time as the others and suffered heavy losses. Lee's army continued its retreat into the Shenandoah Valley after the battle.

The Potomac Mills was a mill complex located along the Potomac River roughly .5 miles (0.80 km) downriver of Shepherdstown. Built in 1826, the complex was originally used as a gristmill. In 1829, the mill began producing cement for the Chesapeake and Ohio Canal's construction. The factory continued to produce cement after the canal opened, and it shipped its product along the canal to other cities. Flooding and drought conditions in the 1880s led the mill to reduce its operations, and by 1901 the mill closed permanently.The remaining buildings from the mill occupy an 18-acre (7.3 ha) site and are mostly in ruins. The buildings include the main mill building, several lime kilns, a headrace wall, and an office building. The stone foundation of the mill's dam, which extends across the river into Washington County, Maryland, is also still part of the site. The mill site was added to the National Register of Historic Places on February 5, 2014.
