The Joint Council of Municipalities in Croatia (Croatian: Zajedničko vijeće općina; Serbian: Заједничко веће општина/ Zajedničko veće opština; shortly: ЗВО / ZVO) is an elected consultative sui generis body which constitutes a form of cultural self-government of Serbs in the eastern Croatian borderland Danube region. The body was established in the initial aftermath of the Croatian War of Independence as a part of the international community's efforts to peacefully settle the conflict in self-proclaimed Eastern Slavonia, Baranya and Western Syrmia. The establishment of the ZVO was one of the explicit provisions of the Erdut Agreement which called upon the United Nations to establish its UNTAES transitional mission.
