Yafforth is a village and civil parish in North Yorkshire, England about 1 mile (1.6 km) west of Northallerton.

It is thought that the name Yafforth is derived from Ea-ford, meaning the ford in the river.

[2] Yafforth was mentioned in the Domesday Book as a berewick in the royal manor of Northallerton.

[3] To the north of the village lies a notable mound called Howe Hill, It is a Norman motte probably built during the reign of King Stephen.

Today it still stands 15 feet (4.6 m) high and retains some of its ditch and the counter scarp bank.
