 
The 2019 Chicago elections took place in two rounds on February 26, 2019, and April 2, 2019. Elections were held for Mayor of Chicago, City Clerk of Chicago, City Treasurer of Chicago, and all 50 members of the Chicago City Council. The candidates who won in these elections were inaugurated on May 20, 2019. Four ballot referendums were also voted on in certain precincts. The elections were administered by the Chicago Board of Elections.
Mayor.
Incumbent mayor Rahm Emanuel announced on September 4, 2018, that he would not run for re-election, reversing his previous announcement that he would run. Fourteen candidates appeared on the ballot in the first round election on February 26, 2019. Since no candidates won 50% of the vote, the top two vote-getters advanced to a run-off election. These candidates were former President of the Chicago Police Board Lori Lightfoot and Cook County Board President Toni Preckwinkle. In the general election on April 2, 2019, Lightfoot defeated Preckwinkle, winning with 73.7% of the vote.
