Sturzkampfgeschwader 3 (StG 3—Dive Bomber Wing 3) was a Dive bomber wing in the German Luftwaffe during World War II and operated the Junkers Ju 87 Stuka.
The wing was activated on 9 July 1940 using personnel from German medium bomber and other dive-bomber units. StG 3 was one of the few dive bomber units created during the war.
StG 3 fought its first campaign in the Battle of Britain a short time after formation. In 1941 it served in the Balkans Campaign and then some groups served on the Eastern Front, from 1943, until disbanded.
The wing operated through most of the North African Campaign and some of its units fought to destruction there. StG 3 also served in the Battle of the Mediterranean and spearheaded the last German campaign-sized victory in the Dodecanese campaign in autumn 1943.
The wing redesignated to Schlachtgeschwader 3 (Battle Wing) on 18 October 1943.
