Municipalities in Bosnia and Herzegovina

In Bosnia and Herzegovina, the smallest administrative unit is the municipality ("opština/општина" or "općina/опћина" in the official languages and scripts of the country). Prior to the 1992–95 Bosnian War there were 109 municipalities in what was then Socialist Republic of Bosnia and Herzegovina. Ten of these formed the area of the capital Sarajevo.

After the war, the number of municipalities was increased to 142, grouped in the following way:

79 municipalities constitute the Federation of Bosnia and Herzegovina (FBiH), which comprises 51% of the country's total territory. The municipalities within the federation are grouped into ten cantons.
64 municipalities constitute the Republika Srpska (RS), which comprises 49% of the country's total territory.

In addition, Brčko District does not belong to either entity and is governed as a condominium of both FBiH and RS entities. The district corresponds to the pre-war Brčko municipality. Although technically not called a municipality, it is treated as such for statistic purposes.

Administratively, each municipality has a municipality council and a municipality head, and they usually consist of an urban area with the surrounding villages and rural areas around it. Bosnia and Herzegovina also has 32 officially designated cities: Banja Luka, Bihać, Tuzla, Mostar, Zenica, Doboj, Prijedor, Bijeljina, Trebinje, Široki Brijeg, Cazin, Goražde, Livno, Zvornik, Gradiška, Živinice, Gračanica, Srebrenik, Gradačac, Visoko, Ljubuški, Čapljina, Derventa, Lukavac, Zavidovići, Konjic, Bosanska Krupa, Orašje, Stolac and Laktaši each correspond to a single eponymous municipality. The cities of Sarajevo and Istočno Sarajevo consist of four and six municipalities respectively, which roughly correspond to the ten pre-war municipalities which constituted the capital city.
