The Ministry of National Defence of the Republic of Lithuania (Lithuanian: Lietuvos Respublikos krašto apsaugos ministerija) is government institution in Lithuania responsible for the organization of national defence.

The first decree concerning the national defence was issued on 23 November 1918, which is officially considered the day of the formation of the Lithuanian Armed Forces.

As soon as Lithuania began forming its defence institutions, the country had to mobilize and fight the Lithuanian Wars of Independence.
