The 2022 Cook County Board of Commissioners election saw all seventeen seats of the Cook County Board of Commissioners up for election to four-year terms. The election coincided with other 2022 Cook County, Illinois, elections (including an election for the president of the Board of Commissioners) with the primary elections held on June 28, 2022^[1] and the general election held on November 8, 2022.^[2]

As this was the first elections held following the 2020 United States Census, the seats faced redistricting before this election.^[3] A new map was unanimously adopted by the Cook County Board of Commissioners in September 2021.^[4]

Democrats won an increased majority with 16 seats, while Republicans won only a single seat (a net gain of one seat for Democrats and net loss of one seat for Republicans). Thirteen incumbent members won reelection (12 Democrats and 1 Republican). Three incumbent members did not seek reelection (2 Democrats and 1 Republican). One member (a Democrat) was unseated in their primary. A single seat, held by a retiring Republican, changed parties. The Democratic Party ran nominees for all seventeen seats. The Republican Party ran nominees for eleven seats, an increase from the eight seats they ran nominees for in 2018. The Libertarian Party, which had run no nominees in the 2018 election, ran nominees for four seats in 2022.
