柏林-勃兰登堡普鲁士宫殿园林基金会

The Prussian Palaces and Gardens Foundation Berlin-Brandenburg (German: Stiftung Preußische Schlösser und Gärten Berlin-Brandenburg; SPSG) was founded by a treaty of 23 August 1994 between the German federal states of Berlin and Brandenburg as a public foundation following German reunification. The treaty came into force on 1 January 1995.

The foundation is separate from the considerably larger Prussian Cultural Heritage Foundation (Stiftung Preußischer Kulturbesitz).
