The 2011 San Francisco mayoral election was held on Tuesday, November 8, 2011, to elect the mayor of San Francisco. The incumbent Ed Lee, appointed to fill the vacant mayoral seat, succeeded in his bid to become the first elected Asian-American mayor of a major American city.

## Background

Gavin Newsom, first elected in 2003 and reelected in 2007, was elected Lieutenant Governor of California in 2010 and sworn in on January 10, 2011. Ed Lee was appointed by the San Francisco Board of Supervisors to finish the balance of Newsom's mayoral term and was sworn in on January 11, 2011. Lee initially pledged not to seek election, although an active movement arose to draft him into the race. By the end of July observers were expecting that Lee would agree to run. On August 8, 2011, Lee announced he was running for Mayor of San Francisco.
The mayoral election was run using instant runoff voting, which was adopted by a referendum in 2002. This voting method was first in effect for the 2007 mayoral election, but no transfers of votes were needed in 2007 since incumbent mayor Gavin Newsom received a majority of the first round votes.

## Candidates

There were sixteen candidates running:
* Jeff Adachi, Public Defender of San Francisco
* Michela Alioto-Pier, former member of the San Francisco Board of Supervisors from District 2
* Cesar Ascarrunz, nightclub owner and community service entrepreneur, mayoral candidate in 1979, 1983, 1987, 1991, and 1999
* John Avalos, member of the San Francisco Board of Supervisors from District 11
* Terry Baum, playwright and actress
* David Chiu, President of the San Francisco Board of Supervisors, member of the San Francisco Board of Supervisors from District 3
* Paul Currier
* Bevan Dufty, former member of the San Francisco Board of Supervisors from District 8
* Tony Hall, former member of the San Francisco Board of Supervisors from District 7
* Dennis Herrera, City Attorney of San Francisco
* Emil Lawrence
* Ed Lee, incumbent Mayor of San Francisco
* Wilma Pang, City College of San Francisco professor
* Joanna Rees, venture capitalist
* Phil Ting, Assessor-Recorder of San Francisco
* Leland Yee, California State Senator from California's 8th State Senate district

### 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.

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.
