Jagdgeschwader 50 (JG 50), sometimes erroneously referred to as Jagdgruppe 50, was a special high-altitude fighter unit that was intended to be specialized in intercepting the Royal Air Force's de Havilland Mosquito light bombers during World War II.

On 21 July 1943, Jagdgruppe Süd der ObdL was formed as a high-altitude fighter unit to combat the RAF's Mosquito twin-engine bomber and reconnaissance aircraft. On 15 August 1943 the unit was redesignated Jagdgeschwader 50 and was commanded by Major Hermann Graf, the first pilot in history to achieve 200 aerial victories. Both JG 50 (and its sister unit Jagdgeschwader 25) were ultimately unsuccessful in effectively countering the Mosquito and were more successfully used for interception of the US heavy bomber formations during the daylight offensive over Europe in 1943-44. Only one Mosquito was taken down, and even that is subject to dispute.

JG 50 were initially equipped with eight Messerschmitt Bf 109G-5s and Bf 109G-6s polished to increase speed, and equipped with a special internal tank for liquefied nitrous oxide as part of the GM-1 engine power boosting system, which was injected directly into the supercharger intake. This allowed the pilot to boost the rated horsepower of the DB 605 engine. The unit was later also equipped with specially supercharged FW-190A-5.

Graf was allowed to pick any pilots he wished for the new unit, and he chose a further three aces Alfred Grislawski, Ernst Süß, and Heinrich Füllgrabe from his old unit - the 9. Staffel of JG 52. Graf was charged with assessing new methods of attacking American bomber formations. JG 50 was the first formation to use the Werfer-Granate 21 rocket mortar, with one carried under each wing. While these rockets could bring down a bomber with one hit, they were designed to disperse the combat boxes of Allied aircraft rather than as a direct fire weapon.
