Cade's Road is a postulated Roman Road in north-east England. It is named after John Cade of Durham, an 18th-century antiquarian who in 1785 proposed its existence and possible course from the Humber Estuary northwards to the River Tyne, a distance of about 100 miles (160 km). Although evidence exists for such a road on some parts of the proposed route, there is still some doubt regarding its exact course. The road's Roman name is unknown.
