Geneva (Swiss German Gämf, Gänf, Genf; French Genève [ʒənɛv, ʒnɛv]; French Provençal Geneva [ðəˈnɛva, ˈzɛnəva]; Italian Ginevra; Rhaeto-RomanicAudio-Datei / Hörbeispiel Genevra? /i) is a city and political commune and the capital of the canton of Geneva in Switzerland.

The city is located at the southwestern tip of French-speaking Switzerland (Romandie) in the Lake Geneva region at the outflow of the Rhone from Lake Geneva. With its 203,951 inhabitants (December 31, 2019), Geneva is the second largest city in Switzerland after Zurich. 47.9 percent of its residents do not have Swiss citizenship, making Geneva one of the Swiss cities with a very high proportion of foreigners, along with Basel and Lausanne. The statistical population density of 12,835 inhabitants per square kilometer is extremely high by Swiss standards. The metropolitan region of Geneva-Lausanne, with 1.2 million inhabitants, is an extended conurbation and is the most important in French-speaking Switzerland.

Along with New York City, the city of Geneva is home to most of the world's international organizations, including the UN, CERN, ICRC, WHO, ILO, IOM, ISO, IEC, ITU, WIPO, WMO, WOSM and WTO. Together with Basel (Bank for International Settlements), New York City (UN headquarters) and Strasbourg (Council of Europe), Geneva is one of the few cities in the world that serves as the headquarters of one of the international organizations commonly considered most important without being the capital of a state. In addition, 175 states have diplomatic representation here; for example, some maintain diplomatic representation in Switzerland in Geneva rather than in the federal city of Bern.

Geneva is the second largest financial center in Switzerland after Zurich, followed by Lugano. In a ranking of the most important financial centers worldwide, Geneva ranks 26th (as of 2018).

For years, Geneva has been listed alongside Zurich and Basel as part of the ten cities with the best quality of life in the world and at the same time with the highest global cost of living. In 2018, 18.6 percent of the population were millionaires (calculated in US dollars). This makes Geneva the city with the second-highest millionaire density in the world, behind Monaco.
