Oštro koplje (, which means Sharp Spear; sometimes also called Barjak (Барјак), which means Flag) is a highest mountain peak in southern Kopaonik mountains in Kosovo. At 1789m high it is the second highest mountain in the Kosovan part of Kopaonik. Because of its height the mountain and its surroundings are treeless. To the south of the mountain are the large villages of Kačandol and Bajgora.
