Langley or Langley-on-Tyne is a small village in Northumberland, England, located to the west of Hexham. The village is on the A686 about 3 miles (5 km) south of Haydon Bridge. The skyline of Langley on Tyne is still dominated by the lead smelting chimney with its underground flue leading to the old smelt works, now a sawmill, where the old tracks for the ore wagons can still be seen. There are currently just over 100 residents.
