St. Louis, Missouri, held general elections for the Board of Aldermen on April 4, 2023. All 14 seats on the board and the seat of the president of the board were up for election. Eleven incumbents, including Board President Megan Ellyia Green, won re-election. Three incumbents were defeated.
The 2023 elections were the first to take place under a new ward system that reduced the number of seats on the board from 28 to 14. Voters approved Proposition R, a charter amendment requiring the size reduction, in 2012, and the board enacted a new 14-ward map in 2021.
Ahead of the election, KDSK’s Sam Clancy and Mark Maxwell wrote, “For more than a century, 28 members of the Board of Aldermen governed the City of St. Louis. Those days are almost over.”
