Lanchester is a village and civil parish in County Durham, England, and was in the former district of Derwentside (1975–2009). It is to the west of the city of Durham and from the former steel town of Consett, and has a population of slightly more than 4000.
Although there was a small drift mine on the edge of the village which closed in the 1970s, Lanchester's economy was mainly based on agriculture. It is now a residential village in which a number of housing estates have been developed since the late 1960s. The village centre now has three pubs and a small shopping centre. Thanks to the Lanchester Partnership, a cycle track was opened on 25 April 2009.
