The 2022 United States House of Representatives elections in Illinois were held on November 8, 2022, to elect the 17 U.S. representatives from Illinois, one from each of the state's 17 congressional districts (reduced from 18 in the redistricting cycle following the 2020 United States census). The elections coincided with the 2022 U.S. Senate race in Illinois, as well as other elections to the House of Representatives, other elections to the United States Senate and various state and local elections. On November 23, 2021, Governor J. B. Pritzker signed the Illinois Congressional Redistricting Act of 2021, which established the new boundaries of the districts, into law. FiveThirtyEight ranked Illinois as the most gerrymandered Congressional map drawn by Democrats following 2022 redistricting.
Before the 2020 redistricting cycle, the 1st district was primarily based in the South Side of Chicago. Under the new congressional map, although the 1st district is still based in Chicago, including portions of Bronzeville, Hyde Park, Grand Crossing, Morgan Park, and Roseland, it now reaches down to the southwest and takes in a collection of exurban and rural areas in Cook County, Will County, and Kankakee County. The former section is heavily black and the latter is heavily white; as a result, the district as a whole is slightly over 50% black. The incumbent was Democrat Bobby Rush, who was re-elected with 73.8% of the vote in 2020. On January 3, 2022, Rush announced that he would retire rather than seek a sixteenth term in office.
The incumbent was Democrat Robin Kelly, who was re-elected with 78.8% of the vote in 2020.
During the 2020 redistricting process, the Illinois General Assembly decided to create a second Latino-influenced district. As such, the 3rd congressional district had no incumbent. The district is approximately 47% Latino and unites heavily Latino communities from Chicago to Elgin. Among potential voters, the communities in the district include 63.4% White, 25.2% Latino, 6.2% Black, and 4.7% Asian people. It includes parts of the Chicago neighborhoods of West Town, Logan Square, Humboldt Park, Belmont Cragin, Portage Park, Irving Park, Albany Park, Montclare, Dunning, and all or parts of the suburbs of Elmwood Park, River Grove, Franklin Park, Bensenville, Elk Grove Village, Wood Dale, Addison, Glendale Heights, Wheaton, West Chicago, Wayne, Bartlett, Hanover Park, and Elgin.
The incumbent was Democrat Jesús "Chuy" GarcÃÂa, who was re-elected with 84.1% of the vote in 2020.
The incumbent was Democrat Mike Quigley, who was re-elected with 70.8% of the vote in 2020.
Due to redistricting, the borders of several districts in the Chicago area changed dramatically. 3rd District Incumbent Marie Newman was drawn into the Latino-majority 4th District. As a result, Newman decided to switch to the redrawn 6th district and announced that she would be running against 6th district incumbent Sean Casten. The new district contains about 40% of Newman's old district and about 25% of Casten's. In the opening stages of the campaign both Casten and Newman declared an intent to run on their legislative records, and declared that they would not campaign negatively against each other.
The incumbent was Democrat Danny Davis, who was re-elected with 80.4% of the vote in 2020. He was running for re-election.
The incumbent was Democrat Raja Krishnamoorthi, who was re-elected with 73.2% of the vote in 2020.
The incumbent was Democrat Jan Schakowsky, who was re-elected with 71.0% of the vote in 2020.
The incumbent was Democrat Brad Schneider, who was re-elected with 63.9% of the vote in 2020.
The incumbent was Democrat Bill Foster, who was re-elected with 63.3% of the vote in 2020.
The incumbents were Republican Mike Bost, who was re-elected with 60.4% of the vote in 2020, and Republican Mary Miller, who was redistricted from the 15th Congressional District.
Due to redistricting, the 13th congressional district was created as a new seat, with no incumbent.
The incumbent was Democrat Lauren Underwood, who was re-elected with 50.7% of the vote in 2020. The 14th district as drawn during the 2020 redistricting cycle includes all or parts of Aurora, DeKalb, Granville, Joliet, Montgomery, Naperville, Oswego, Ottawa, Peru, Plainfield, Shorewood, Spring Valley, Sugar Grove, and Sycamore.
Incumbent Republican Mary Miller then represented the 15th congressional district, and was running for re-election in the district. Due to redistricting, Republican Rodney Davis, who represented the 13th congressional district, resided in the 15th district and opted to run in the new 15th district rather than the more Democratic 13th. The new 15th district, located in western and central Illinois, includes all or parts of Adams, Bond, Brown, Calhoun, Cass, Coles, DeWitt, Edgar, Greene, Hancock, Henderson, Jersey, Logan, Macon, Madison, Mercer, Menard, Montgomery, Morgan, Pike, Sangamon, Schuyler, Scott, Shelby, Christian, Vermillion, and Warren counties.
The incumbents were Republican Adam Kinzinger, who was re-elected with 64.7% of the vote in 2020, and Republican Darin LaHood, who was redistricted from the 18th Congressional District. Kinzinger chose to retire, while LaHood chose to run in his new district.
The incumbent was Democrat Cheri Bustos, who was re-elected with 52.0% of the vote in 2020. She did not seek re-election in 2022.
The new 17th was drawn to be more Democratic-leaning than its predecessor. The new district contains nearly all of its Democratic-leaning urban portions of its former territory, while most of the Republican-leaning areas of the old 17th were drawn into the neighboring 15th and 16th districts. Had the new 17th existed in the 2020 election, Joe Biden would have carried it by eight points, whereas Donald Trump carried the old 17th by two points in 2020.
