The 2025 Bornholm Municipal election will be held on November 18, 2025, to elect the 23 members to sit in the regional council for the Bornholm Municipal council, in the period of 2026 to 2029.[1]
In the 2021 election, Red–Green Alliance became the largest party. However, it was Jacob Trøst from the Conservatives, who became mayor.[2]
Former mayor, and latest mayoral candidate for the Social Democrats, Thomas Thors announced a few days following the 2021 election that he would stop in politics.[3]
For elections to Danish municipalities, a number varying from 9 to 31 are chosen to be elected to the municipal council.
The seats are then allocated using the D'Hondt method and a closed list proportional representation.
Unlike in Danish General Elections, in elections to city councils, electoral alliances are allowed.
