Auvergne (; ; or ) is a former administrative region in central France, comprising the four departments of Allier, Puy-de-Dôme, Cantal and Haute-Loire. On 1 January 2016, the region was merged with surrounding historical regions to form a new first-level administrative region of Auvergne-Rhône-Alpes.
The administrative region of Auvergne is larger than the historical province of Auvergne, one of the seven counties of Occitania, and includes provinces and areas that historically were not part of Auvergne. The Auvergne region is composed of the following old provinces:
Velay, Gévaudan, and Vivarais are often considered to be sub-provinces of the old province of Languedoc. Forez is also often considered to be a sub-province of Lyonnais. Therefore, the modern region of Auvergne is composed of the provinces of Auvergne, part of Bourbonnais, and parts of Languedoc and Lyonnais.
Auvergne had an area of , which is 4.8% of France's total area. Auvergne was one of the smallest regions in France during its existence.
Auvergne was bordered by the administrative regions of Centre-Val de Loire and Burgundy to the north, Rhône-Alpes to the east, Languedoc-Roussillon and Midi-Pyrénées to the south, and Limousin.
