Octavian's military campaigns in Illyricum (35-33 B.C.) constitute the first attempt by the future emperor Augustus to occupy the Illyrian area, shortly after achieving a definitive victory over Sextus Pompey and before the final and decisive clash with his fellow triumvir, Mark Antony.

In the course of the Illyrian War, Octavian conquered (in addition to some less serious foes) the Iapodes, parts of Pannonia around Segestica/Siscia, as well as the Delmatae. However, the majority of the future provinces of Pannonia and Dalmatia were subdued by Tiberius during his Pannonian War (12–9 BC) and Pannonian-Dalmatian Rebellion (AD 6–9). These conflicts were initiated by preparations for war against Maroboduus, particularly through the recruitment of soldiers in Illyricum.

Suetonius tells us that Octavian:

"[...] during the war in Dalmatia he was also wounded: in combat he was struck by a stone in the right knee, in another clash he was wounded in the leg and arms by the collapse of a bridge."
— Suetonius, Augustus, 20).
