The city of Chicago, Illinois held a nonpartisan mayoral election on Tuesday, February 22, 2011. Incumbent Mayor Richard Michael Daley, a member of the Democratic Party who had been in office since 1989, did not seek a seventh term as mayor. This was the first non-special election since 1947 in which an incumbent mayor of Chicago did not seek reelection.

Candidates needed to collect 12,500 petition signatures by November 22, 2010, to qualify for a place on the ballot. April 5, 2011 was scheduled to be a runoff election date if no candidate received an absolute majority.

Rahm Emanuel won the race for mayor with more than 55% of the vote. He was inaugurated on May 16, 2011.

The election saw what was, at the time, the most candidates running on the ballot of any Chicago mayoral election since 1919. This would be surpassed by the 2019 Chicago mayoral election.

Candidates Nominating petitions were filed for 20 candidates in November 2010. In the initial review of the petitions by the Chicago Board of Election Commissioners on December 6, 2010, three candidates, Ryan Graves, M. Tricia Lee, and Jay Stone, were removed from the ballot for submitting insufficient numbers of signatures or duplicate signatures, although they had the right to seek reconsideration of the decision. Rob Halpin, businessman and tenant of Rahm Emanuel, withdrew from the election on the same day. Tom Hanson was removed by the Board of Election Commissioners on December 13, but filed a complaint in Circuit County Court Chancery division seeking reversal of the Board's decision, for being contrary to Illinois Election Code, Section 10–8, but was not reinstated.Circuit Court of Cook County following Tom Hanson's judicial petition to reverse the Election Board of Commissioners' decision Former U.S. Senator from Illinois Roland Burris withdrew from the race on December 17, 2010.

Eligibility of Emanuel On January 24, 2011, Rahm Emanuel was removed from the ballot by the Illinois First District Appellate Court in a 2–1 decision. Emanuel's eligibility had been previously confirmed by the Chicago Board of Election Commissioners and a judge of Cook County. Emanuel appealed the case to the Supreme Court of Illinois. Chicago Tribune and Chicago Sun-Times criticized the ruling in editorials as "startling arrogance and audaciously twisted reasoning" and "pinched interpretation of the law [that] ignores the lawmakers' obvious intent". On January 25, 2011, the Supreme Court of Illinois issued a stay of the appellate court's ruling that Rahm Emanuel should be removed from the ballot. On January 27, 2011, the Supreme Court of Illinois, in a unanimous (7–0) decision, overturned the ruling of the Appellate Court and allowed Emanuel to stay on the ballot.

Campaign

On September 23, 2010, Miguel del Valle became the first candidate to launch a television commercial in the mayoral race.

Rahm Emanuel announced his resignation as White House Chief of Staff on October 1, 2010, and went on to announce his mayoral candidacy on October 3. According to the Chicago Sun-Times, two Chicago election lawyers stated that Illinois municipal code requires mayoral candidates to reside in the town for a year before the election, making Emanuel ineligible to hold the office. On December 23, 2010, the Chicago Board of Election Commissioners unanimously rejected the challenge to Emanuel and ruled that he was a legal resident of Chicago.

The editorial pages of Chicago Tribune and Chicago Sun-Times endorsed Rahm Emanuel on February 4, 2011.

While President Barack Obama had not formally endorsed Emanuel, there was a public perception that the president favored his former Chief of Staff for mayor.
