Lyon (Franco-Provençal: Liyon) is a city in France. It is located at the confluence of the rivers Rhône and Saône, to the northwest of the French Alps, 391 km (243 mi) southeast of Paris, 278 km (173 mi) north of Marseille, and 113 km (70 mi) southwest of Geneva, Switzerland.
The City of Lyon is the third-largest city in France with a population of 520,774 at the January 2022 census within its small municipal territory of 48 km (19 sq mi), but together with its suburbs and exurbs the Lyon metropolitan area had a population of 2,327,861 that same year, the second largest in France. Lyon and 58 suburban municipalities have formed since 2015 the Metropolis of Lyon, a directly elected metropolitan authority now in charge of most urban issues, with a population of 1,433,613 in 2022. Lyon is the prefecture of the Auvergne-Rhône-Alpes region and seat of the Departmental Council of Rhône (whose jurisdiction, however, no longer extends over the Metropolis of Lyon since 2015).
