A by-election was held in the Western Australian Legislative Assembly district of Fremantle on 16 May 2009. It was triggered by the resignation of sitting member Jim McGinty. The Labor Party was defending a seat that they had held continuously since 1924. The by-election was held in conjunction with the state referendum on daylight saving hours. The Greens candidate, Adele Carles, won the by-election, and in doing so became the first Greens candidate to be elected to an Australian state lower house of parliament in a single-member seat.
