The Pipp Brook is a 9.5km long left-bank tributary of the River Mole, Surrey that descends steeply northward then flows east. It rises at two main springs in the Greensand Ridge, receives the Milton Brook which rises at a tri-forked source lower than its own, turns east descending less rapidly before discharging approximately half-way along the Mole's meandering northward course at Dorking.
