Kampfgeschwader 30 (KG 30) was a Luftwaffe bomber wing during World War II.

KG 30 was equipped with the Junkers Ju 88 and was initially trained as an anti-shipping and maritime attack unit: at the start of October 1939 it was attached to X. Fliegerkorps.

On 16 October 1939 it attacked naval ships anchored off Rosyth Dockyard in the Firth of Forth.

The unit lost four Ju 88s in the action, the highest single loss of KG 30 throughout the campaign.

On 17 June 1940 bombers from II./KG 30 sank RMS Lancastria off St Nazaire as she evacuated troops during Operation Aerial, killing some 5,800 Allied personnel.
