Stony Run is a tributary stream of Jones Falls in Baltimore, Maryland. The stream headwaters are in north Baltimore near the city boundary. The stream flows southward about 3miles past several Gilman School, Cathedral of Mary Our Queen, and Friends School of Baltimore, following the former Ma and Pa Railroad route[1] [2] and through Wyman Park. It enters a culvert before emptying into Jones Falls near Druid Hill Park.[3]
