Jagdgeschwader 3 or JG 3 was a fighter wing of the Luftwaffe during WWII. It served in all theaters of war that Germany participated in except for North Africa. It was originally formed in 1939 and it served until the end of the war. JG 3 operated mainly Messerschmitt Bf 109s and Focke Wulf Fw 190s during the war but by the end, they had been one of few squadrons to have received new Messerschmitt Me 262 jet fighters.
