Neuenkirchen (German pronunciation: [ˈnɔʏənˌkɪʁçn̩] ⓘ; Low German: Neekark) is a municipality in the Altes Land, district of Stade, Lower Saxony, Germany.

Neuenkirchen belonged - as to its government - to the Prince-Archbishopric of Bremen, established in 1180.

[2] In religious respect, however, Neuenkirchen formed part of the Roman Catholic Diocese of Verden until after 1566 its incumbent bishops lost papal recognition, except of a last Catholic bishop from 1630 to 1631, respectively.

[2] In 1648 the prince-archbishopric was transformed into the Duchy of Bremen, which was first ruled in personal union by the Swedish – interrupted by a Danish occupation (1712–1715) – and from 1715 on by the Hanoverian Crown.

In 1813 the duchy was restored to the Electorate of Hanover, which – after its upgrade to the Kingdom of Hanover in 1814 – incorporated the duchy in a real union and the ducal territory, including Neuenkirchen, became part of the Stade Region, established in 1823.
