The General Defense Command (防衛総司令部 Bōei Soshireibu?) was a headquarters organization equivalent to an army group within the Imperial Japanese Army established to control all land and air units stationed within Japan proper, Korea and Taiwan during the Pacific War.

The General Defense Command was also responsible for anti-aircraft defenses, and for organizing civil defense training.
