The Broken Hills is a range of low-lying mountains and ridges in northern Fauquier County, Virginia.
The range begins just to the west of the southern Bull Run Mountains, north of Warrenton, Virginia and continues westward to the eastern edge of Blue Ridge Mountain. Interstate 66 and Virginia State Route 55 run just north of the range, while US-211 runs to the south. The stretch of US-17 between Warrenton and Marshall traverses the range.
The Broken Hills form the southern border of the Loudoun Valley.
