Local elections were held in Belgrade on 17 December 2023 to elect members of the City Assembly. Initially scheduled to be held by 2026, the election was called earlier after Aleksandar Vučić, the president of Serbia, announced in September 2023 that the election could be held in December 2023. In response to the announcement, Aleksandar Šapić, the mayor of Belgrade, tendered his resignation. Šapić ceased being mayor on 30 October 2023, when the Temporary Council of Belgrade was established. The elections were held concurrently with the parliamentary, Vojvodina provincial, and the local elections in 64 cities and municipalities in Serbia.

The City Assembly of Belgrade is the legislature of Belgrade, the capital city of Serbia.
