The Grand Council of Geneva (French: Grand Conseil de Genève) is the legislature of the canton of Geneva, in Switzerland. Geneva, styled as a 'Republic and Canton', has a unicameral legislature. The Grand Council was established in its present form and with 100 seats in 1842, with members elected every four years. Its oldest ancestor is the Council of Two Hundred (with 200 seats), founded in 1526. Members of the canton's executive, the Council of State, are elected a month later.
There is a 7% threshold that political parties wishing to be represented on the Grand Council must overcome. Seven parties did so at the most recent election, held on 15 April 2018.
