The Intelligenzaktion Pommern was a Nazi German operation aimed at the eradication of the Polish intelligentsia in Pomeranian Voivodeship and the surrounding areas at the beginning of World War II. It was part of a larger genocidal Intelligenzaktion that took place across most of Nazi-occupied western Poland in the course of Operation Tannenberg (Unternehmen Tannenberg), purposed to install Nazi officials from SiPo, Kripo, Gestapo and SD at the helm of a new administrative machine.
