Free war (Swedish: fria kriget) is a form of guerrilla warfare that is conducted with cut-off smaller military units in enemy occupied territory. The largest difference between free war and guerrilla warfare is that free war is conducted by regular military forces, instead of paramilitary organizations or irregular military forces.

The term is most often associated with the Swedish military,^{[citation needed]} primarily during the Cold War era. Though Sweden no longer has free war in their official doctrine, there are still military manuals that mention and deal with this subject.

During the Cold War, conducting free war was to some degree a part of the military training curriculum in Sweden, where the purpose was to enable every conscript soldier to conduct free war in the case of enemy occupation of Sweden.^[1]
