Headlam is a village in the borough of Darlington and the ceremonial county of County Durham, England. It lies to the west of the town of Darlington. The population taken at the 2011 Census was less than 100. Details are included in the parish of Ingleton. It is a picturesque hamlet of just 14 stone houses plus 17th-century Headlam Hall, now a country house hotel. The village is set around a village green with a medieval cattle-pound and an old stone packhorse bridge across the beck. Headlam is classed as Lower Teesdale and has views to the south as far as Richmond and to the Cleveland Hills in the east.
In the Imperial Gazetteer of England and Wales (1870–72) John Marius Wilson described Headlam:
Headlam was originally a township in the ancient parish of Gainford in County Durham. It became a separate civil parish in 1866. From 1894 it was part of Barnard Castle Rural District. According to A Vision of Britain through Time between 1974 and 2009 Headlam became part of the larger Teesdale non-metropolitan district, but Wikipedia states it was and is in the Borough of Darlington. It is possible that the transfer from Teesdale to the Borough of Darlington took place in 2009 when the Teesdale District became part of County Durham unitary authority and the Borough of Darlington continued to be a separate unitary authority. A road map of 2014 puts Headlam on the Teesdale side of the boundary.
