Puy-de-Dôme (French: [pɥi də dom] ^ⓘ; Auvergnat: lo Puèi de Doma or lo Puèi Domat) is a department in the Auvergne-Rhône-Alpes region in the centre of France. In 2021, it had a population of 662,285.^[3] Its prefecture is Clermont-Ferrand and subprefectures are Ambert, Issoire, Riom, and Thiers.

Named after the Puy de Dôme dormant volcano, its inhabitants were called Puydedomois in French until 2005. With effect from 2006, in response to a letter writing campaign, the name used for the inhabitants was changed by the Puy-de-Dôme General Council to Puydômois; this is the name that has since then been used in all official documents and publications.

Puy-de-Dôme is one of the original 83 departments created during the French Revolution on 4 March 1790. It was created from part of the former province of Auvergne. Originally, the department was to be called Mont-d'Or ("Golden Mountain"), but this was changed to Puy-de-Dôme following the intervention of Jean-François Gaultier de Biauzat, a local deputy, because of a concern that the name originally chosen risked attracting excessive unwelcome attention from the national taxation authorities.

Puy-de-Dôme is part of the current region of Auvergne-Rhône-Alpes and is bordered by the departments of Loire, Haute-Loire, Cantal, Corrèze, Allier, and Creuse. Parts of the department belong to the Parc naturel régional des Volcans d'Auvergne and Parc naturel régional Livradois-Forez.

The department is in the Massif Central and boasts more than 80 volcanic craters. It is three hours from Paris and an hour from Lyon by highways A71 and A89. The A75 links it to the Mediterranean Sea.

The most populous commune is Clermont-Ferrand, the prefecture. As of 2021, there are 10 communes with more than 10,000 inhabitants:^[3]
