Royal Prussian Jagdstaffel 65, commonly abbreviated to Jasta 65, was a "hunting group" (i.e., fighter squadron) of the Luftstreitkräfte, the air arm of the Imperial German Army during World War I. The squadron would score 34 aerial victories during the war, including nine observation balloons downed. The unit's victories came at the expense of six pilots killed in action, two wounded in action, and two taken prisoner of war.
