Ambert (French pronunciation: [ɑ̃bɛʁ] ⓘ; Auvergnat: Embèrt) is a commune in the Puy-de-Dôme department in Auvergne in central France.

Ambert is famous for its fourme d'Ambert cheese - "Fourme d'Ambert", its paper mills - "Le moulin Richard de Bas" - (the first edition of Diderot's Encyclopédie was printed on paper made in Ambert) and its circular town market hall - "La Mairie" - (popularized by Jules Romains in his novel Les copains).

[4] There is a steam engine that makes a local run, but to see the line in full a ride on the Panoramique Autorail is not to be missed.

There is an industrial museum with an interesting collection of tractors and small steam engines.

Ambert was the birthplace of the mathematician Michel Rolle (1652–1719), composer Emmanuel Chabrier (1841–1894), and anthropologist Henri Pourrat (1887–1959), who collected the oral traditions of the Auvergne.
