Lynemouth is a village in Northumberland, England. It is 3 miles northeast of Ashington, and is close to the village of Ellington, which is to the north west. The village was built close to coal mines.
Lynemouth and the surrounding industrial area played an important role in the 1985 feature-length docudrama Seacoal about the seacoalers, who made a living from collecting waste coal from the beach. A series of photographs within the Henri Cartier-Bresson Award–winning book In Flagrante (1988) by Chris Killip shows the work and life of the seacoalers here; a greater number were published in 2011 in the book Seacoal.
Also, the village can be seen in the 2000 film Billy Elliot. Lynemouth Cemetery doubles as Everington Cemetery, in which Elliot's mother is buried. The colliery, which was demolished in 2005, can be seen in scenes filmed at the cemetery.
To the south of the village is the former Alcan Lynemouth Aluminium Smelter, now closed, and power station.
An electoral ward in the same name exists. This ward stretches north along the coast to Craster with a total population taken at the 2011 Census of 4,842.
