Prussian Cultural Heritage Foundation

The Prussian Cultural Heritage Foundation (German: Stiftung Preußischer Kulturbesitz; SPK) is a German federal government body that oversees 27 museums and cultural organizations in and around Berlin, Germany. Its purview includes all of Berlin's State Museums, the Berlin State Library, the Prussian Privy State Archives and a variety of institutes and research centers. As such, it is one of the largest cultural organizations in the world, and also the largest cultural employer in Germany with around 2,000 staff as of 2020. More than four million people visited its museums in 2019.

The SPK was established in 1957 with the mission to acquire and preserve the cultural legacy of the former State of Prussia. Its current operations include the preservation and care of the museum collections and the continuation of academic and scientific research to encourage learning and understanding between different peoples.

Hermann Parzinger became president of the foundation in 2008. In July 2024 Marion Ackermann, until then responsible for the Staatliche Kunstsammlungen Dresden, was announced to become new president by the foundations governing body by June 2025.
