The Périgord ( pronunciation (help·info)) (Occitan: Peiregòrd / Perigòrd) is a natural region and former province of France, which corresponds roughly to the current Dordogne département, now forming the northern part of the Aquitaine région. It is divided into four regions, the Périgord Noir (Black), the Périgord Blanc (White), the Périgord Vert (Green) and the Périgord Pourpre (Purple). The geography and natural resources of Périgord make it a beautiful, unspoiled region rich in history and wildlife, and the newly created Parc Naturel Régional Périgord-Limousin aims to conserve it as such.

The area is noted for its cuisine, more particularly its products related to ducks and geese, such as foie gras. It is one of the truffle areas of France, historically the most famous. Périgourdine wines include the famed Bergerac (red and white) and Monbazillac.

The préfecture (capital) of the Dordogne is Périgueux. Bergerac in the south and Sarlat in the east are the sub-prefectures. There are Roman ruins in Périgueux which have been restored and the whole area is known as the 'cradle of mankind' due to its wealth of prehistoric sites, of which the most famous prehistoric site is the painted cave of Lascaux, whose depictions of aurochs, horses, deer and other animals (but not of humans) date back some 17,000 years.
