Grenoble (/ɡrəˈnoʊbəl/ grə-NOH-bəl; French: [ɡʁənɔbl] ; Arpitan: Grenoblo or Grainóvol; Occitan: Graçanòbol or Grenòble) is the prefecture and largest city of the Isère department in the Auvergne-Rhône-Alpes region of southeastern France. It was the capital of the Dauphiné historical province and lies where the river Drac flows into the Isère at the foot of the French Alps.

The population of the commune of Grenoble was 158,198 as of 2019, while the population of the Grenoble metropolitan area (French: aire d'attraction de Grenoble or agglomération grenobloise) was 714,799 which makes it the largest metropolis in the Alps, ahead of Innsbruck and Bolzano. A significant European scientific centre, the city advertises itself as the "Capital of the Alps", due to its size and its proximity to the mountains. The many suburban communes that make up the rest of the metropolitan area include four with populations exceeding 20,000: Saint-Martin-d'Hères, Échirolles, Fontaine and Voiron.

The Isère (US: /iːˈzɛər/ ee-ZAIR, French: [izɛʁ] ; Arpitan: Isera; Occitan: Isèra) is a river in the Auvergne-Rhône-Alpes region of southeastern France. Its source, a glacier known as the Sources de l'Isère, lies in the Vanoise National Park in the Graian Alps of Savoie, near the ski resort in Val-d'Isère on the border with Italy. An important left-bank tributary of the Rhône, the Isère merges with it a few kilometers north of Valence.

Many riverside communes have incorporated the Isère's name into their own, for example, Sainte-Hélène-sur-Isère and Romans-sur-Isère. The department of Isère is likewise named after the river.

It is the fourth-largest commune in the Isère department, of which it is a subprefecture alongside La Tour-du-Pin. Vienne was a major centre of the Roman Empire under the Latin name Vienna.

Vienne was the capital of the Allobroges, a Gallic people, before its conquest by the Romans. Transformed into a Roman colony in 47 BC under Julius Caesar, it became a major urban centre, ideally located along the Rhône, then a major axis of communication. Emperor Augustus banished Herod the Great's son, the ethnarch Herod Archelaus to Vienne in 6 AD.

The Dauphiné was originally the Dauphiné of Viennois.

In the 12th century, the local ruler Count Guigues IV of Albon (c. 1095–1142) bore a dolphin on his coat of arms and was nicknamed le Dauphin (French for 'dolphin'). His descendants changed their title from Count of Albon to Dauphin of Viennois. The state took the name of Dauphiné. It became a state of the Holy Roman Empire in the 11th century.
