The Battle of Dubravnica was fought in the summer of 1380 or December 1381, on the Dubravnica River near Paraćin in today's central Serbia, between the Serbian forces of Prince Lazar of Serbia led by commanders Vitomir and Crep and the invading Ottoman Turks of Sultan Murad I. Vitomir and Crep were the regional lords, and one of their fortresses, Petrus, was in the vicinity of the battle.
The Battle of Dubravnica was the first historical mention of any Ottoman movements into Prince Lazar's territory. The Serbian army emerged victorious, although details of the battle itself are scarce. After this battle the Turks didn't venture into Serbia until 1386, when their armies were routed near Pločnik.
