The 2003 San Francisco mayoral election occurred on November 4, 2003. The incumbent, Willie Brown, was termed out of office and could not seek a third term. The general election included three top candidates including then Supervisor Gavin Newsom and then president of the board of supervisors, Matt Gonzalez and former supervisor Angela Alioto. No candidate received the required majority, so the race went into a run-off of the two top candidates, which were Gavin Newsom and Matt Gonzalez. The run-off occurred on December 9, 2003, where Gavin Newsom was elected mayor of San Francisco.
