The minister of defence of Hungary (Hungarian: Magyarország honvédelmi minisztere) is a member of the Hungarian cabinet and the head of the Ministry of Defence.

The defence minister appoints the Chief of General Staff of the Hungarian Defence Forces.

The current minister is Kristóf Szalay-Bobrovniczky.

The position was called People's Commissar of War (Hungarian: hadügyi népbiztos) during the Hungarian Soviet Republic in 1919 and Minister of War (Hungarian: hadügyminiszter) during two short periods of Hungarian history: at the time of the Hungarian Revolution of 1848 and during a very short chaotic term (less than two years) after World War I, when three political transformations took place.

From 1867 to 1918 there was a Honvédministerium responsible for the military of the Hungarian half of Austria-Hungary and a Ministry of Defence for the military of the Austrian half, along with a Ministry of War with responsibility for Austria-Hungary as a whole.
