Royal Prussian Jagdstaffel 39, commonly abbreviated to Jasta 39, was a "hunting group" (i.e., fighter squadron) of the Luftstreitkräfte, the air arm of the Imperial German Army during World War I. The unit would score 68 aerial victories during the war, including 14 observation balloons downed. The squadron's victories came at the expense of seven pilots killed in action, one killed in a flying accident, five wounded in action, and one taken prisoner of war.
