Mayoral elections
2021 :
vte :
Elections were held in Illinois on Tuesday, November 5, 1940.
Primaries were held April 9, 1940.
While the Democratic ticket of Franklin D. Roosevelt and Henry A. Wallace won the state's electors in the presidential election, the election overall saw significant victories for the Republican Party. The Republican Party retained their control of the Illinois House, and flipped control of the Illinois Senate, as well as control of the executive offices of Governor, Lieutenant Governor, Attorney General, Auditor of Public Accounts, and Treasurer, all of which had previously been under Democratic Party control. Democrats retained their hold on the executive office of Secretary of State. Additionally, Republicans won all seats up for election on the Board of Trustees of the University of Illinois. Republicans also won the state's special United States Senate election and flipped 6 Illinois seats in the United States House of Representatives.

## Election information
