2009 Geneva Grand Council election

The 2009 election to the Grand Council was held in the canton of Geneva, Switzerland, on 11 October 2009. All 100 members of the Grand Council were elected for four-year terms.

The Liberal Party remained the largest party, with twenty seats, having lost three since 2005. The centre-right 'Entente', between the Liberals, Free Democratic Party, and Christian Democrats lost a total of five seats. The main winners were the populist Geneva Citizens' Movement, who almost doubled their number of seats to draw level with the Green Party as the second-largest contingent. The far left alliance between solidaritéS and the Swiss Party of Labour failed to overcome the 7% threshold for representation, despite each having each separately received more than 6% at the 2005 election.
