Jagdgeschwader 77 (JG 77) Herz As ("Ace of Hearts") was a Luftwaffe fighter wing during World War II. It served in all the German theaters of war, from Western Europe to the Eastern Front, and from the high north in Norway to the Mediterranean.

All three gruppen (groups) within the unit operated variants of the Messerschmitt Bf 109. II. Gruppe was the only German unit entirely equipped, albeit only during November–December 1943, with the Macchi C.205, a highly regarded Italian fighter.
