Auvergne (/oʊˈvɛərn(jə), oʊˈvɜːrn/; French: [ovɛʁɲ] ^ⓘ; Occitan: Auvèrnhe or Auvèrnha) is a cultural region in central France. It is now largely part of the Auvergne-Rhône-Alpes administrative region.

Auvergne is generally regarded as conterminous with the land area of the historical Province of Auvergne, which was dissolved in 1790, and with the now-defunct administrative region of Auvergne, which existed from 1956 to 2015.

The region is home to a chain of volcanoes known collectively as the "chaîne des Puys". The volcanoes began forming about 70,000 years ago, and most have eroded, leaving plugs of hardened magma that form rounded hilltops known as puys. The last confirmed eruption occurred around 4040 BCE.

Auvergne is known for its mountain ranges and dormant volcanoes. Together the Monts Dore and the Chaîne des Puys include 80 volcanoes. The Puy de Dôme is the highest volcano in the region, with an altitude of 1,465 metres (4,806 ft). The Sancy Massif in the Monts Dore is the highest point in Auvergne at 1,886 metres (6,188 ft).

The northern part is covered in hills, while the southern portion is mountainous and dotted with pastures. The Forest of Tronçais covers nearly 11,000 hectares (27,000 acres) and is the largest oak forest in Europe.

Auvergne has two major rivers: the Loire runs through the southeast and borders the northeast, and the Allier runs from north to south down the center of Auvergne, with branches going east and west.

Auvergne has about 50 freshwater ponds and lakes. Some are high in the mountains and have volcanic origins. Lac de Guéry is the highest lake in Auvergne.

The average annual temperature is 12 °C (54 °F), and the region receives 510 to 1,020 mm (20 to 40 in) of rainfall annually.
