Wade's Causeway is a sinuous, linear monument up to 6,000 years old in the North York Moors national park in North Yorkshire, England. The name may refer to either scheduled ancient monument number 1004876—a length of stone course just over 1 mile (1.6 km) long on Wheeldale Moor, or to a postulated extension of this structure, incorporating ancient monuments numbers 1004108 and 1004104 extending to the north and south for up to 25 miles (40 km). The visible course on Wheeldale Moor consists of an embankment of soil, peat, gravel and loose pebbles 0.7 metres (2.3 ft) in height and 4 to 7 metres (13 to 23 ft) in width. The gently cambered embankment is capped with unmortared and loosely abutted flagstones.
