Drôme (French pronunciation: [dʁom]; Droma in Occitan, Drôma in Arpitan) is a department in southeastern France named after the Drôme River.


St Vallier in Drôme, was the birthplace of one of France's most famous courtesans, the noble-born Diane de Poitiers (1499-1566), long-term mistress of King Henri II (1547-1559).

The French National Constituent Assembly set up Drôme as one of the original 83 departments of France on March 4, 1790, during the French Revolution. The territory formed part of the former French province of Dauphiné.


Drôme lies within the region of Auvergne-Rhône-Alpes and is surrounded by the departments of Ardèche, Isère, Hautes-Alpes, Alpes-de-Haute-Provence and Vaucluse.

The boundaries of the department have changed several times with the incorporation of the Comtat Venaissin in 1792 and the creation of the Vaucluse department in 1793. Drôme surrounds an exclave of the Vaucluse department, the Canton of Valréas (Enclave des Papes).


The Drôme department is in a zone of transition between the oceanic climate of Lyon, the continental climate to the north and the Mediterranean climate of Provence to the south. In the Rhône valley, the meeting of the mild humid southern Mediterranean air masses with the colder northern air mass sometimes causes particularly violent thunderstorms and snowstorms.

In the northern hills near Tain-l'Hermitage (15 km north of Valence), the climate is a mixture of oceanic and semi-continental climates. Rainfall occurs throughout the year with the most falling in spring and autumn. The summers are moderated by storms and the mistral does not blow hard. Saint-Donat-sur-l'Herbasse has a moderate temperature of 3 °C in January and 21 °C in July due to the Lyonnic climate, where more precipitation falls in summer than winter.

The influence of the mountains is evident in the east. In the Vercors Plateau, the mountain climate is wet due to the oceanic influences from the north. The average annual temperature at Lus la Croix Haute at altitude 1061m is 7.3 °C and the annual rainfall is 1051mm. The Diois (southern Vercors) and the Baronnies are dry regions due to the Mediterranean climate. The mistral is less influential here and this region has minimal rainfall. The lowest temperatures in January at Nyons is 0.3 °C but 1.4 °C at Pierrelatte.

The Valence plane is a transition zone between the Mediterranean influence and the northern cold climate. Summers are warmer than in the northern regions, and the increase in sunlight and heat is evident upon the appearance of Mediterranean vegetation in the region. The temperatures are moderate between Lyon and Montélimar. Valence's average temperature in January is 3.8 °C and 22 °C in July. The mistral here blows harder.

From Montélimar, the climate can be considered to be that of a Mediterranean climate. Near the highway, the change of vegetation is particularly visible near the stream at Donzère, particularly due to the change of the soil profile. The most southern part of the department clearly exhibits a Méso-Mediterranean climate with the reinforcement of the mistral and a hotter summer due to the rarity of storms. Most rainfall occurs in autumn and the winters are milder than the rest of the Drôme. Pierrelatte has an average temperature of 5 °C in January and 23 °C in July.


Most of the economic activity of the Drôme department is located in the west of the department, along the Rhône valley. This area which contains most of the population of the department, also has accessible transportation, such as the A7 autoroute and the rail routes LGV Rhône-Alpes and LGV Méditerranée. Economic activity in Valence, Drôme was boosted by the creation of the Valence TGV line in 2001.
