The Federal Ministry of Defence (German: Bundesministerium für Landesverteidigung, sometimes shortened to BMLV or Verteidigungsministerium) of Austria is the ministry in charge of all matters relating to military affairs, especially the Austrian Armed Forces.

The minister is head of all the ministry's subordinate authorities and is the Supreme Military Commander of the Austrian Armed Forces.

For certain acts, such as deployment of more than 5,000 men of the militia or reserve, the Minister for Defence's authorization is bound to the President of Austria, since in these cases the constitutional command of the army takes precedence.

The defence ministry took on various names during the First Austrian Republic of 1918 to 1938, and was abolished during Nazi Germany's annexation of Austria from 1938 to 1945.

Sport first became a government portfolio in Austria in 1966, as part of the remit of the Federal Ministry of Education, which in 1984 was renamed the Federal Ministry of Education, Arts and Sports.
