Shenandoah, a river of Virginia, the principal tributary of the Potomac. The main river, or South fork, rises in Augusta and Rockingham cos. in three streams which unite near Port Republic, Rockingham co., flows N. E. through the valley of Virginia, W. of and nearly parallel with the Blue Ridge, receives the North fork at Front Royal, Warren co., and falls into the Potomac at Harper's Ferry, W. Va.
