2024 Bosnian municipal elections

Municipal elections will be held in Bosnia and Herzegovina on 6 October 2024 to elect mayors and assemblies in 143 municipalities.

Electoral system
Municipal elections in Bosnia and Herzegovina comprise the election of a mayor and municipal assembly across the 143 municipalities of Republika Srpska and the Federation of Bosnia and Herzegovina. They are governed by the Law on Elections.

Mayors are elected by a first-past-the-post system, with the candidate receiving the plurality of votes winning. For this reason, multi-party coalitions are more common at the mayoral level, with a united political or ethnic slate presented in situations where several candidates may divide the electorate. Assembly elections use open list proportional representation, with the number of assembly members varying by population.

Sarajevo and Istočno Sarajevo are further subdivided into four and six municipalities which also elect assemblies and then, indirectly, mayors. The Brčko District is considered an independent self-administrative unit, electing an assembly which in turn selects a mayor. Mostar will hold elections using the mixed-member proportional representation system where 22 seats will be elected in six different city areas and 13 on the city list. The mayor will be elected by the city assembly. It will also be the second elections in Mostar after the political agreement in 2020 and the first to be held in the same time as the rest of the country since 2008.

There are 31 seats in the Assembly of the Brčko District. The seats are divided as follows as of the 2020 municipal elections:
