Sleepy Creek is a 44adj=midNaNadj=mid[1] tributary of the Potomac River in the United States, belonging to the Chesapeake Bay's watershed. The stream rises in Frederick County, Virginia, and flows through Morgan County, West Virginia before joining the Potomac near the community of Sleepy Creek.
While Sleepy Creek Lake is a part of the Sleepy Creek watershed, it is an impoundment of its tributary, Meadow Branch, in Berkeley County, West Virginia and not of Sleepy Creek itself.
Sleepy Creek's source lies north of State Route 127 in Frederick County, Virginia, near the Hampshire County, West Virginia border at Good. From Frederick County, Sleepy Creek flows north through Morgan County, West Virginia, where it drains into the Potomac at the community of Sleepy Creek on the old Baltimore and Ohio Railroad's mainline.
Tributary streams listed from south (source) to north (mouth).
