This is a list of Serbianparamilitary units and formations throughout history. It includes Serbian volunteer militias loyal to the Habsburg Monarchy prior to Serbian independence, and organizations loyal to Serbia since. Note that many of the organizations either started out or ended up folded into official military organizations. These are distinct from institutions with formal status and a direct leadership structure under a nation-state, examples being the World War I era First Serbian Division and the post-2006 modern Serbian Army, which do not belong on this list.
