The United States Senate election in Illinois of 1950 was held on November 7, 1950[1] to elect one of Illinois's members to the United States Senate. Republican Everett Dirksen defeated incumbent Democratic Senator and Senate Majority Leader Scott W. Lucas, who had been seeking a third term.
Dirksen carried 82 of the state's 102 counties.[1] Among the 88 counties that Dirksen won was the state's most populous county, Cook County, in which Dirksen won with 50.01% to Lucas' 49.60%.[1] Despite losing in Cook County, Lucas performed better in the county than he did in the cumulative vote of the remaining 101 counties,[1] where Dirksen won 57.56% to Lucas' 42.13%.[1] 54.54% of the votes cast in the election were from Cook County.[1]
Lucas was the second-ever Senate leader to lose re-election, and the only one to do so while his party retained the majority. Coincidently, Dirksen himself later became the Republican Senate leader in 1959.
