Yeading Brook 16 miles (26 km) is a tributary of the River Crane, in West London. It rises in major part from the Headstone Manor moat, and in minor part from a small stream flowing from Pinner Park (which is also the source of the River Pinn). It follows a meandering course through North Harrow, Rayners Lane, Ruislip, South Ruislip (skirting RAF Northolt as it does so where it joins the Roxbourne Brook shortly thereafter), and onwards to Southall, before its confluence with the Crane at Hayes.
