() is a ( or ), a public entity under Swiss law, in charge of organizing cooperation within the cross-border metropolitan area of Geneva (in particular metropolitan transports). The Grand Genève GLCT extends over Switzerland (entire Canton of Geneva and the canton of Vaud's entire Nyon District) and France (, literally "Metropolitan hub of the French Genevan territory", a federation of eight French intercommunal councils in the departments of Ain and Haute-Savoie).
The Grand Genève GLCT covers a land area of (27.7% Swiss territory, 72.3% French territory) and had a population of 1,046,168 in Jan. 2021 (Swiss estimates and French census), 58.3% of them living on Swiss territory, and 41.7% on French territory.
The city centre of Geneva is located only from the border of France. As a result, the urban area and the metropolitan area largely extend across the border on French territory. Due to the small size of the municipality of Geneva () and extension of the urban area over an international border, official bodies of transnational cooperation were developed as early as the 1970s to manage the cross-border Greater Geneva area at a metropolitan level.
In 1973, a Franco-Swiss agreement created the ('Franco-Genevan Regional Committee', in French). In 1997 an 'Urban planning charter' of the CRFG defined for the first time a planning territory called ('Franco-Vaud-Genevan urban area'). 2001 saw the creation of a ('Strategic Committee for the Development of Regional Public Transports', in French), a committee which adopted in 2003 a 'Charter for Public Transports', first step in the development of a metropolitan, cross-border commuter rail network (see Léman Express).
In 2004, a public transnational body called ('Franco-Vaud-Genevan urban area project') was created to serve as the main body of metropolitan cooperation for the planning territory defined in 1997, with more local French councils taking part in this new public body than in the CRFG created in 1973. Finally in 2012 the was renamed ('Greater Geneva'), and the following year it was transformed into a Local Grouping of Transnational Cooperation (), a public entity under Swiss law, which now serves as the executive body of the .
