1883 Chicago mayoral election

The Chicago mayoral election of 1883 was held on Tuesday April 3, saw incumbent Carter Harrison Sr. defeat Republican Eugene Cary by a double-digit margin.

By winning the 1883 election, Harrison became the second mayor in Chicago history to be elected to a third term (after only Francis Cornwall Sherman), and the first to be elected to a third consecutive term.

By the day of the election, Harrison was already the second-longest serving mayor in the city's history, and was only roughly a month shy of surpassing Monroe Heath as the longest serving mayor.

Harrison's 15% margin of victory was the greatest in all of his campaigns for mayor.

Harrison's opponent, Eugene Cary, was a member of the Chicago Common Council that had previously been county judge and city attorney in Sheboygan, Wisconsin and had also served as a member of the Tennessee Senate.
