Drôme (French pronunciation: [dʁom] ; Occitan: Droma; Arpitan: Drôma) is the southernmost department in the Auvergne-Rhône-Alpes region of Southeastern France. Named after the river Drôme, it had a population of 516,762 as of 2019. Drôme's prefecture is Valence.

The southern portion of the Drôme, closest to Provence, is often known as the fr:Drôme Provençale.

The French Prealps (French: Préalpes françaises [pʁealp fʁɑ̃sɛːz]) are a group of subalpine mountain ranges of medium elevation located immediately west of the French Alps. They roughly stretch from Lake Geneva southwest to the rivers Isère and Drôme; east to a line running from Chamonix, to Albertville, to Grenoble, to Gap, to Barcelonette; and south from Grasse to Vence.

In the northern subalpine regions, the various ranges are easily identifiable by geographical separations, such as the Voreppe Gorge between Vercors and Chartreuse, or Chambéry, which sits in a valley between the Bauges and Chartreuse ranges. In the southern subalpine regions, the ranges are generally disorganized and lack the wide, deep valleys that divide them in the north.

The Bez (also: Bès) is a tributary to the river Drôme in the Drôme department of France. It is 25.5 km (15.8 mi) long. It has a drainage basin of 278 km².
