Sleepy Creek Mountain is a mountain ridge in the Ridge-and-Valley Appalachians on the border between Morgan and Berkeley counties in the Eastern Panhandle of West Virginia. The long-distance Tuscarora Trail traverses the southern ridge and northern bench of the mountain. Together with Third Hill Mountain to the east, the two mountains form a blind valley that contains Sleepy Creek Lake and the Sleepy Creek Wildlife Management Area. Sleepy Creek and Third Hill Mountains are distinctive for their height in the relatively level terrain of the far Eastern Panhandle of West Virginia.
