Carlat is a commune in the Cantal department in south-central France.

The "Rocher de Carlat" or rock of Carlat situated above the picturesque commune was once the site of one of the most powerful and impenetrable chateaux in all of France. It was the seat of Jacques d'Armagnac, Duke of Nemours and often the center of intrigue, resistance and rebellion against the kings of France. Completely razed by order of the king in 1604 to alleviate the inconvenience of rebellious and ambitious southern relatives, hardly a trace of the chateau remains. The site is now a park, open to visitors and commanding sweeping views of the Carlades.
