Broad Run is a 38.0-mile-long (61.2 km)[1] tributary of the Occoquan River in the U.S. state of Virginia.

It rises in Fauquier County and passes through Thoroughfare Gap.

[2] The creek should not be confused with the nearby Broad Run (a tributary of the Potomac River) that flows through Loudoun County, Virginia.

It ultimately feeds the Chesapeake Bay Watershed.
