The Democratic Opposition of Serbia (Serbian: Демократска oпозиција Cрбије / Demokratska opozicija Srbije) commonly referred to as DOS was a wide alliance of democratic political parties in Serbia intent on ousting the ruling Socialist Party and its leader Slobodan Milošević. Its presidential candidate Vojislav Koštunica defeated Milosevic in the 2000 general election while the DOS secured a majority of seats in the National Assembly.
