Steinkirchen (German: Steinkirchen im Alten Land, Low German: Steenkark) is a municipality in the district of Stade, Lower Saxony, Germany.

The municipality is located in the Altes Land, the largest continuous orchard and fruit harvesting region in Europe. It is situated by the Elbe and Lühe rivers and is bordered by the municipalities (in clockwise order) Grünendeich, Jork, Mittelnkirchen, Guderhandviertel, Agathenburg and Hollern-Twielenfleth. The southeasterly third of the Elbe island Lühesand forms part of the municipal area.

It belonged to the Prince-Archbishopric of Bremen. In 1648 the Prince-Archbishopric was transformed into the Duchy of Bremen, which was first ruled in personal union by the Swedish and from 1715 on by the Hanoverian Crown. In 1823 the Duchy was abolished and its territory became part of the Stade Region.
