Randan (in French pronounced as /ʁɑ̃dɑ̃/; Occitan (post 1500);: Randans) is a commune in the Puy-de-Dôme department in Auvergne-Rhône-Alpes in central France.
The place gives its name to Randanite, a soluble silica that occurs as fine earth near Randan and near Algiers.In the late 19th century the official composition of the dynamite at the Poudrerie nationale de Vonges and other French powder works was 75% nitroglycerin, 20.8% randanite, 3.8% Vierzon silica and 0.4% magnesium carbonate.
Randan was a holiday destination of the royal family of the House of Orléans in the early nineteenth century, thanks to the Château in Randan.
