The Defence Headquarters Complex (Sinhala: ආරක්ෂක හමුදා මුලස්ථානය, romanized: ārakshaka hamudā mūlasthānaya) is a complex of buildings at Akuregoda, Sri Jayawardenapura Kotte to house the Sri Lanka Armed Forces headquarters and offices of the Ministry of Defence.

The headquarters of various defence institutions were separate and scattered across Colombo, resulting in great inefficiency and high-security zones amidst commercial areas, causing disturbance to the general public.

This increases operational, administrative and logistic efficiency and minimises the disturbances caused to civilians and economic activities.

In addition there is another block of similar size separate from the administrative complex as a communications center alongside other buildings.
