Kampfgeschwader 1 (KG 1) (Battle Wing 1) was a German medium bomber wing that operated in the Luftwaffe during World War II.
KG 1 was created in 1939 as the Luftwaffe reorganised and expanded to meet Adolf Hitler's rearmament demands. It was founded in May 1939 and by December 1939, had three active Gruppen (Groups). In August 1940 a fourth Gruppe was added. KG 1 operated the Heinkel He 111 medium bomber and later the Heinkel He 177 heavy bomber.
KG 1 served in the Invasion of Poland on 1 September 1939 which began the war in Europe. It spent the Phoney War on reconnaissance operations and dropping propaganda leaflets over France. In May and June 1940 it fought in the Battle of Belgium and Battle of France. In July 1940, the force took part in the Battle of Britain and The Blitz.
In June 1941 it supported Operation Barbarossa, the invasion of the Soviet Union. Elements of the bomber wing remained on the Eastern Front for the duration of the conflict. KG 1 also served intermittently in the Italian Campaign from March–August 1943. All KG 1 Gruppen ceased to exist by September 1944 and were merged with other Luftwaffe units before the German capitulation in May 1945.
