Langen bei Bremerhaven is a town and a former municipality in the district of Cuxhaven, in Lower Saxony, Germany. Since 1 January 2015 it is part of the town Geestland. It is situated approximately 7 km north of the centre of Bremerhaven, and 30 km south of Cuxhaven.
Langen belonged to the Prince-Archbishopric of Bremen, established in 1180. In 1648 the Prince-Archbishopric was transformed into the Duchy of Bremen, which was first ruled in personal union by the Swedish Crown - interrupted by a Danish occupation (1712–1715) - and from 1715 on by the Hanoverian Crown. The Kingdom of Hanover incorporated the Duchy in a real union and the Ducal territory became part of the new Stade Region, established in 1823.
