The Musić (Serbian Cyrillic: Мусић, pl. Мусићи) was a Serbian noble house that served the Serbian Empire (1345–1371), and during its fall (1371–1389) it served Tsar Lazar's Serbia. The eponymous founder was čelnik Musa, who married Dragana Hrebeljanović, the sister of Tsar Lazar (r. 1371-1389). Stefan and Lazar Musić, the sons of Musa, held a region of roughly modern Raška municipality and north Kosovo. The brothers died fighting the Ottoman Empire in the Battle of Kosovo (1389).
