2023 Chicago aldermanic election

The elections are non-partisan and use a two-round system where the top two finishers compete in a second-round runoff if no candidate receives more than 50% of the vote in the first round.

Sixteen seats changed hands since the previous election, as 12 alderpersons did not run for re-election and 4 additional members resigned during their terms.
