Short Hill Mountain is a mountain ridge of the Blue Ridge Mountains in northwest Loudoun County, Virginia.

Short Hill rises sharply from the Piedmont countryside of the Loudoun Valley, northwest of Purcellville, as a low-lying ridge barely over 400 feet (120 m) above the surrounding area. The mountain ridge extends northeast for approximately 3 miles (4.8 km) before descending to the Hillsboro Gap, through which the North Fork of flows and the town of Hillsboro is located. North of the gap, the ridge quickly achieves heights of greater than 600 feet (180 m) above the gap, and continues for 12 miles (19 km), gradually gaining elevation, before dropping precipitously to the Potomac River.

The portion of the mountain south of Hillsboro Gap is known as Signal Mountain for the Union Army signaling station located on its 1,020 feet (310 m) summit during the American Civil War. North of the Potomac, the ridge continues as South Mountain in Maryland and Pennsylvania.

Short Hill is about 4 miles (6.4 km) east of the crest of the Blue Ridge Mountain, which forms the western border of Loudoun County, and the valley in between the mountains is known as Between the Hills and includes the villages of Loudoun Heights and Neersville. To the east of the mountain is the .

A small portion of Short Hill on its northwestern slope, along the Potomac, is owned by the National Park Service to preserve downriver views for Harpers Ferry National Historical Park. The rest of the mountain is in private hands and is by and large undeveloped. The only road crossing of the mountain is Virginia State Route 9 at Hillsboro.
