The Battle of Bliska (present day Blizna in the hinterland of Trogir called Zagora, southern Croatia) was fought in 1322 between the army of a coalition of several Croatian noblemen and Dalmatian coastal towns (with the support of the king Charles I Robert of Anjou) and the forces of Mladen II ubi of Bribir, Ban of Croatia, and his allies. The battle resulted in the defeat of Mladen II, who lost his power.

Mladen II Šubić of Bribir (Croatian: Mladen II Šubić Bribirski, Hungarian: bribiri Subics Mladen; c.1270 – c.1341), a Croatian leader and member of the Šubić noble family, was a Ban of Croatia and Lord of all of Bosnia. After succeeding his father Paul, he further consolidated the Šubić domain, and brought Stephen Kotromanić to administer Bosnia under his overlordship. His subsequent rule marked the weakening of the Šubić and ended with a mutiny of Dalmatian cities and Croatian nobility in 1322. This further led to Mladen's deposition and imprisonment by king Charles I of Hungary, whom the Šubićs had previously brought to the throne in Hungary with the help of other lords. Mladen continued to develop the state and court institutions, and his de facto rule led to the further development of the chivalric culture in Croatia.
