Jasionowo is a village in the administrative district of Gmina Lipsk, within Augustów County, Podlaskie Voivodeship, in north-eastern Poland, close to the border with Belarus.[2] It is located within the historic Suwałki Region (Suwalszczyzna).
In 1827, the village had a population of 47.[3]
During the German occupation of Poland (World War II), on 2 August 1943, the Germans pacified the village in an act of anti-Polish revenge after losing an officer in a battle with the Polish resistance. They surrounded the village and shot all the captured villagers, i.e. 58 Poles, including 19 children, and destroyed houses and outbuildings.[4] [5]
