Sturzkampfgeschwader 1 (StG 1 - Dive Bomber Wing 1) was a Luftwaffe dive bomber wing during World War II. StG 1 was formed in May 1939 and remained active until October 1943, when it was renamed and reorganised into Schlachtgeschwader 1 (SG 1). It operated the Junkers Ju 87 Stuka dive-bomber exclusively in the combat role. StG 1 served the German war effort on every front including limited Bandenbekämpfung operations in support of Wehrmacht and Nazi paramilitary forces.
