The Ministry of Defence (MoD) () is a Bangladeshi government ministry. The MoD is headed by the Minister of Defence, a civilian and member of cabinet. The post is usually held by the Prime Minister of Bangladesh, who also serves as the President's second-in-command of the military. The MoD exercises supreme command authority over the Bangladesh Armed Forces.

Organisational structure
Parliament is constitutionally responsible for working with the president and the service chiefs in ensuring the nation's defence. In practice, however, members of Parliament have never played a significant role in either national defence planning or defence budgeting, the Defence Secretary does.
