Lune is a river in Lower Saxony, Germany. It is some 41 kilometres (25 mi) long and a right tributary of the Lower Weser.

The Lune is a small lowland river, which is joined initially by the Volkmarster Lune on the boundary between the borough of Bremervörde and the district of Cuxhaven. Between Kirchwistedt and Stemmermühlen is its confluence with the Altwistedter Lune, and it then flows through Beverstedt, Lunestedt, Nesse [de; nl] near Loxstedt and Lanhausen [de; nds] to the Lunesiel south of the Fischereihafen district [de; pl] of Bremerhaven. Until the beginning of the 17th century the river was a major transport artery and navigable until Deelbrügge (nowadays a district of Beverstedt). It was named after the explorer Gerhard von Lune who lived between 1602 and 1666
