Treignac (French pronunciation: [tʁɛɲak]; Occitan: Trainhac) is a commune in the Corrèze department in central France.

Treignac, designated one of the 'most beautiful villages of France', is a most typically French town retaining much of its medieval character, situated on the banks of the Vezere River on one of the pilgrimage routes to Santiago de Compostella, the burial place of St James the Apostle along the way known as the Via Lemovicensis and crosses the 13th-century bridge over the river.

The site is limited to the west by the Rocher des Folles and to the east by the Saut de la Virolle.

The waters of the Vézère are retained upstream of the village by the Barrage de Treignac (dam), forming the lac des Bariousses (lake).

The Chateau was the stronghold of the lands of the Medieval dynasty the Vicomte de Comborn, who had as its first head the man known as Archambaud the butcher, as result of his cruel rule.

The Fleyssac house was built in the 15th century against the ramparts and buttresses of the gate of Pradelle, it was sold to the Protestants in 1638, where they celebrated their worship for the following 50 years.
