Vayrac (French pronunciation: [vɛʁak]; Occitan: Vairac) is a commune in the Lot department in south-western France. The inhabitants of Vayrac are called the Vayracois.

Vayrac is located in the Haut Quercy, in the north of the Lot, in the Valley of the Dordogne Lotoise between Martel and Bretenoux on the D803 and on the edge of the Sourdoire and Maumont rivers.

The commune is bordering the Corrèze department.

The name Vayrac, of Gallo-Roman origin, is based on a surname Varius. The ending -ac is derived from the suffix Gallic -acon (itself from the common Celtic *-āko-), often Latinized in -acum in the texts. This is the domain of Varius.

In the Vayrac commune is found the Gaulish oppidum of the Puy D'issolud (about 300 m above sea level). This site was officially recognised, in April 2001, by the French Ministry of Culture as the site of ancient Uxellodunum, the location of the last battle of Julius Caesar against the rebel Gauls in 51 B.C. post the Battle of Alesia. In addition to an impressive quantity of armaments (Gaulish and Roman arrows), the famous underground galleries have been discovered, made by the sappers of Caesar in order to divert the spring feeding the only source to which the Gauls could come too, to obtain their water supply.

During the Second World War, a number of works of the Louvre Museum were hidden in a barn in Vayrac. On a particularly hot and dry summer day, a fire broke out. The farm workers abandoned their fields to come and form a water-bucket chain and saved the national treasures.
