The Cook County, Illinois, general election was held on November 3, 2020. Elections were held for Clerk of the Circuit Court, State's Attorney, Cook County Board of Review district 1, three seats on the Water Reclamation District Board, and judgeships on the Circuit Court of Cook County.
Primary elections, held using the open primary system, took place on March 17, 2020.

## Election information

The primaries and general elections for Cook County races coincided with those for federal races (President, House, and Senate) and those for state elections.

### Voter turnout
#### Primary election

For the primaries, turnout was 33.54%, with 1,037,951 ballots cast. The ballots cast comprised 957,791 Democratic, 79,669 Republican, and 491 nonpartisan primary ballots. Turnout in the city of Chicago was 37.78%, while turnout in suburban Cook County was 29.42%.
Turnout in the primaries was considered to be low for a presidential primary. The low turnout was attributed by many to the ongoing COVID-19 pandemic. The potentially suppressed turnout of election-day voting as a result of virus concerns was partially offset by high in-person early voting and mail-in ballot numbers. 339,000 people cast early votes, a record number, with Chicago seeing 172,000, and the rest of Cook County seeing 167,000 early votes, a record for each jurisdiction. The election also saw a record number of requests made for mail-in ballots, with both Chicago and the rest of Cook County seeing numbers of requests surpassing any previous election. In Chicago there were 118,000 such requests, with over 80,000 mail-in ballots ultimately being returned and counted. In suburban Cook County, 47,652 mail-in ballots were returned, setting a record. In Chicago, 45% of votes cast were either early votes or votes by mail. In suburban Cook County, 56% of votes cast were either early votes or votes by mail.
The county's turnout was higher than the statewide turnout rate of 28.36%.

#### General election

For the general election, turnout was 72.20%, with 2,349,010 ballots cast. Turnout in the city of Chicago was 73.28%, while turnout in suburban Cook County was 71.18%.
The county, as a whole, saw a turnout that was slightly below the statewide turnout rate of 72.92%.

## Clerk of the Circuit Court

The incumbent fifth-term clerk of the Circuit Court of Cook County, Dorothy Brown, announced in 2019 that she would not run for re-election. Brown had been the subject of a federal corruption investigation when she made the announcement. Democrat Iris Martinez was elected to succeed her.
The last Republican to hold this office was Brown's immediate predecessor Aurelia Pucinski, who, while elected a Democrat in each of her elections to the office, had switched parties in her final term.
