Isère is one of the original 83 departments created during the French Revolution on 4 March 1790. It was established from the main part of the former province of Dauphiné. Its area was reduced twice, in 1852 and again in 1967, on both occasions losing territory to the department of Rhône. • Illustration — The Château de Vizille, which was the seat of the Assembly of Vizille that followed the 1788 Day of the Tiles in Grenoble, now houses the Musée de la Révolution française. In 1852 in response to rapid urban development around the edge of Lyon, the (hitherto Isère) communes of Bron, Vaulx-en-Velin, Vénissieux and Villeurbanne were transferred to Rhône. In 1967 the redrawing of local government borders led to the creation of the Urban Community of Lyon (more recently known simply as Greater Lyon or Grand Lyon). At that time intercommunal groupings of this nature were not permitted to straddle departmental frontiers, and accordingly 23 more Isère communes (along with six communes from Ain) found themselves transferred to Rhône. The affected Isère communes were Chaponnay, Chassieu, Communay, Corbas, Décines-Charpieu, Feyzin, Genas, Jonage, Jons, Marennes, Meyzieu, Mions, Pusignan, Saint-Bonnet-de-Mure, Saint-Laurent-de-Mure, Saint-Pierre-de-Chandieu, Saint-Priest, Saint-Symphorien-d'Ozon, Sérézin-du-Rhône, Simandres, Solaize, Ternay and Toussieu. Most recently, on 1 April 1971, Colombier-Saugnieu was transferred to Rhône. Banners appeared in the commune's three little villages at the time proclaiming Dauphinois toujours ("Always Dauphinois").

Isère includes a part of the French Alps. The highest point in the department is the subpeak Pic Lory at 4,088 m, subsidiary to the 4,102 m Barre des Écrins in the adjoining Hautes-Alpes department. The summit of La Meije at 3,988 m is also well known. The Vercors Plateau aesthetically dominates the western part of the department.

The most populous commune is Grenoble, the prefecture. As of 2023, there were 7 communes with more than 20,000 inhabitants: • Commune — Population (2023) • Grenoble — 156,140 • Saint-Martin-d'Hères — 37,695 • Échirolles — 37,491 • Vienne — 31,778 • Bourgoin-Jallieu — 30,151 • Fontaine — 22,020 • Voiron — 21,847

Inhabitants of the department are called Isérois (masculine) and Iséroises (feminine) in French. Population development since 1801:

The department is served by Alpes–Isère Airport which provides flights to some European destinations. However, other airports such as Lyon–Saint-Exupéry Airport and Geneva Airport are also used by air travellers from the department as both airports provide more domestic and international destinations.

• Illustration — The Grande Chartreuse The Grande Chartreuse is the mother abbey of the Carthusian order. It is located 22 km north of Grenoble. As early as the 13th century, residents of the north and central parts of Isère spoke a dialect of the Franco-Provençal language called Dauphinois, while those in the Southern parts spoke the Vivaro-Alpine dialect of Occitan. Both continued to be spoken in rural areas of Isère into the 20th century.

Isère features many ski resorts, including the Alpe d'Huez, Les Deux Alpes, the 1968 Winter Olympics resorts of Chamrousse, Villard de Lans, Autrans. Other popular resorts include Les 7 Laux, Méaudre, Saint-Pierre-de-Chartreuse, Alpe du Grand Serre and Gresse-en-Vercors. At the department level, Isère is the third-largest ski and winter destination in France, after Savoie and Haute-Savoie. It also hosts Coupe Icare, an annual festival of free flight, such as paragliding and hang-gliding, held at the world-renowned paragliding site at Lumbin. Grenoble has a dozen museums, including its most famous, established in 1798, the Museum of Grenoble. The European Synchrotron Radiation Facility (ESRF), an international research facility in Grenoble, is also open to visitors. • Illustration — Grenoble • Illustration — Ski lift at Alpe d'Huez • Illustration — The Grand Veymont • Illustration — The Dent de Crolles • Illustration — Le Haut-Bréda • Illustration — Queyras Valley • Illustration — Lac de Monteynard-Avignonet • Illustration — Saint-Christophe-sur-Guiers • Illustration — Roman stela nicknamed "the pyramid", Vienne • Illustration — Temple of Augustus and Livia, Vienne
