The 2023 Chicago aldermanic election took place in two rounds on February 28 and April 4, 2023,[2] to elect 50 alderpersons to the Chicago City Council. Each alderperson represents one of Chicago's 50 wards. 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. The elections are part of the 2023 Chicago elections, which include elections for Mayor, City Clerk, and City Treasurer.
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. Media commentators and analysts have noted this unusually high number of retirements, comparing it to the broader "Great Resignation" phenomenon in the United States workforce.[3][4][5][6]
In the first round, candidates in 36 wards won outright majorities while elections in 14 wards proceeded to a runoff election. One incumbent lost in the first round and five others were forced into a runoff, where all five won.[7][1][8] Elected alderpersons took office on May 15, 2023, including a record number of women and LGBT alderpersons. [9] While the elections are non-partisan, 6 candidates endorsed by the Chicago Democratic Socialists of America were re-elected or elected for the first time.[10]
