The 1920 United States Senate election in Illinois took place on November 2, 1920.
Incumbent Republican senator Lawrence Yates Sherman opted to retire rather than seeking reelection. Fellow Republican William B. McKinley was elected to succeed him in office.

## Background

The primaries and general election coincided with those for House and those for state elections, but not those for president. Primaries were held September 15, 1920.
The 1920 United States Senate elections were the first to be held since the Nineteenth Amendment to the United States Constitution granted national women's suffrage. This was the first Illinois U.S. Senate election in which women could vote.
In 1916, incumbent Lawrence Yates Sherman made the decision to retire from politics and to not seek reelection in 1920, due to his failing hearing, which prevented him from hearing what was said on the Senate floor.

## Democratic primary
### Candidates

* Robert Emmet Burke
* Peter A. Waller, Kewanee glove manufacturer

### Campaign

Burke, known as "O.K. Bobby" by supporters, stood on a platform opposed to the League of Nations and ratification of the Treaty of Versailles. He was also opposed to Prohibition and critical of President Wilson. Waller had the support of the Democratic establishment. Neither ran an active campaign.
