The Lower Saxony National Party (Niedersächsische Landespartei) 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. It called for the establishment of a Lower Saxon state within a federal Germany and sought to represent Christian conservatism.
In 1947 after Lower Saxony had been created the party resurrected its old name of the German Party (Deutsche Partei, DP).
