Périgord is a natural region and former province of France, which corresponds roughly to the current Dordogne department, now forming the northern part of the administrative region of Nouvelle-Aquitaine. It is divided into four areas called the Périgord Noir (Black), named so for the truffles that can be found there, the Périgord Blanc (White), for chalk cliffs and quarries, the Périgord Vert (Green), for forests and forestry and the Périgord Pourpre (Purple), for wine and viticulture. The geography and natural resources of Périgord make it a region rich in history and wildlife, and the newly created Parc Naturel Régional Périgord-Limousin aims to conserve it as such.

Dordogne is a large rural department in south west France, with its prefecture in Périgueux. Located in the Nouvelle-Aquitaine region roughly half-way between the Loire Valley and the Pyrenees, it is named after the river Dordogne, which runs through it. It corresponds roughly to the ancient county of Périgord. In January 2023, Dordogne had a population of 412,807.
