|Elections in California|
A special election was held for Mayor of the City and County of San Francisco on June 5, 2018. The winner of the election will serve until 2020, filling the unexpired term of Ed Lee, who was elected in 2011 and 2015, and died in office on December 12, 2017. Upon Lee's death, London Breed, President of the San Francisco Board of Supervisors, became Acting Mayor of San Francisco, but a vote of six supervisors replaced Breed with Supervisor Mark Farrell. The mayoral election was held concurrently with the statewide direct primary election. In San Francisco, the election for the eighth district member of the board of supervisors was also on the ballot.
Eight candidates qualified to appear on the ballot, and a ninth qualified as a write-in. The four major candidates were former Supervisor Angela Alioto, former Acting Mayor London Breed, Supervisor Jane Kim and former state senator Mark Leno. All four main candidates identify as Democrats, though the position is officially nonpartisan per the Constitution of California. Leno conceded the race to Breed on June 13.
Ed Lee, who was appointed Mayor of San Francisco in 2011 following Gavin Newsom's election as Lieutenant Governor of California, elected to a full term in 2011, and reelected in 2015, died of cardiac arrest on December 12, 2017. London Breed, the president of the San Francisco Board of Supervisors, became the city's acting mayor.
On January 23, 2018, the board of supervisors selected Mark Farrell to serve as interim mayor until the special election could be held. Citing Ron Conway's role as a benefactor to Breed, Supervisors Aaron Peskin and Jane Kim, considered the progressive members of the board, sought to deny Breed the benefits of incumbency going into the election.
The filing deadline was 5 p.m. on January 9, 2018.
The following eight candidates qualified for the ballot by filing all nomination documents and paying the filing fee. The deadline for a candidate to drop out of the race and remove himself or herself from the ballot was January 30, 2018.

On June 13, with only 8,000 ballots left to count, Leno conceded defeat and congratulated Breed on her victory.
The following table shows a summary of the instant runoff for the election. The table shows the round in which the candidate was defeated or elected the winner, the votes for the candidate in that round, and what share those votes were of all votes counting for any candidate in that round. There is also a bar graph showing those votes for each candidate and categorized as either first-round votes or votes that were transferred from another candidate.
First Round VotesTransfer Votes

Vote counts by round
The following table shows how votes were counted in a series of rounds of instant runoffs. Each voter could mark which candidates were the voter's first, second, and third choice. Each voter had one vote, but could mark three choices for how that vote can be counted. In each round, the vote is counted for the most preferred candidate that has not yet been eliminated. Then one or more candidates with the fewest votes are eliminated. Votes that counted for an eliminated candidate are transferred to the voter's next most preferred candidate that has not yet been eliminated.
|Candidate||Round 1||Round 2||Round 3||Round 4||Round 5||Round 6||Round 7||Round 8||Round 9|
|Ellen Lee Zhou||9,576||9,576||9,576||9,687||9,829||10,637|
|Amy Farah Weiss||1,675||1,675||1,675||1,735|
|Antoine R. Rogers (Write-in)||3||3|
Continuing votes are votes that counted for a candidate in that round. Exhausted ballots represent votes that could not be transferred because a less preferred candidate was not marked on the ballot. Voters were allowed to mark only three choices because of voting system limitations. Over votes are votes that could not be counted for a candidate because more than one candidate was marked for a choice that was ready to be counted. Under votes are ballots were left blank or that only marked a choice for a write-in candidate that had not qualified as a write-in candidate.
