The 2003 Anchorage mayoral election was held on April 1, 2003, to elect the mayor of Anchorage, Alaska. It saw election of Mark Begich, who unseated incumbent mayor George Wuerch.
An assembly ordinance and ballot proposition passed in Anchorage in 2003 had lowered the threshold required to avoid a mayoral runoff from 50% of the vote to 45%.[1] Since Begich surpassed this margin, no runoff was necessary.
