The OUN Uprising of 1939 (Polish: Dywersja OUN w 1939 roku, Ukrainian: Повстання ОУН 1939 року, romanized: Povstannya OUN 1939 roku) were sabotage actions by supporters and militias of the Organisation of Ukrainian Nationalists carried out during the Invasion of Poland. The uprising was inspired by the Third Reich's interests in weakening Polish forces behind the main front.
