The Lower Saxony State Party (Niedersächsische Landespartei, NLP) was a short lived regionalist political party in Germany.
It was founded in 1945 as a recreation of the regionalist German-Hanoverian Party that had been active in the period between the creation of the German Empire and the rise of the Nazi Party. The NLP called for the establishment of a Lower Saxon state within a federal Germany and sought to represent Christian conservatism.
In 1947, after the state of Lower Saxony had been created, the party adopted the name German Party (Deutsche Partei, DP).
