Jagdgeschwader 77 (JG 77) Herz As ("Ace of Hearts") was a Luftwaffe fighter Geschwader (US "wing"/UK "group") 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 (US "groups"/UK "wings") within the Geschwader operated variants of the Messerschmitt Bf 109. However, II. Gruppe is notable as the only German unit entirely equipped, albeit only during November–December 1943, with the Macchi C.205, a highly regarded Italian fighter.

JG 77 was formed in May 1939 with I. and II. Gruppe. III./JG 77 was formed on 5 July 1940 in Trondheim from the II(J)./JG 186. I./ JG 77 was reorganized on 21 November 1940 into IV./JG 51 and a new I./JG 77 was established. In January 1942 I./JG 77 was transferred to I./JG 5 and a new I./JG 77 was created. In April 1942 1. Staffel was transferred to Romania and designated the defence unit for the Ploieşti oil fields at Mizil. (This staffel was redesignated 1./JG 4 in August 1942.)

I./JG 77 took part in the Invasion of Poland on 1 September 1939, while attached to Luftflotte 3. In April 1940 JG 77 took part in Operation Weserübung, the invasion of Norway. After the invasion of France, I. Gruppe supported 10th Air Corps (under Luftflotte 5) in operations against Britain from bases in Norway. While stationed in Norway and Denmark in 1940 II./JG 77 claimed some 79 victories, for 6 pilots killed, before leaving in November 1940 for defence duties in Brest. In May 1941 II. and III./JG 77 were used in support of the invasion of Greece and the paratroop assault on Crete.
