The 2022 United States Senate election in Illinois was held on November 8, 2022, to elect a member of the United States Senate to represent the state of Illinois.
Incumbent Democratic senator Tammy Duckworth was re-elected for a second term against former U.S. House of Representatives candidate Kathy Salvi, the Republican nominee, winning by a margin of 15.3%, 0.2% more than her 2016 margin. Duckworth became the first woman ever to be re-elected for a second term in the state's history. This was the first Illinois U.S. Senate election where both major party candidates were female.
Salvi flipped seven counties—Calhoun, McDonough, Knox, Gallatin, Pulaski, Alexander, and Madison—that had voted for Duckworth in 2016. On the other hand, Duckworth won Kendall, McLean, Peoria, and Winnebago, which had all voted against her in 2016. With Duckworth's victory, this was the first time since 1986 that a Class 3 Illinois senator was re-elected to a successive six-year term, and the first time since 1992 that any party won the seat consecutively.
