Vaillac (pronounced as /fr/; Languedocien: Valhac) is a former commune in the Lot department in south-western France. On 1 January 2016, it was merged into the new commune of Cœur de Causse.[2]
The village lies in the middle of the commune, in the valley of the Foulon, a stream tributary of the Céou, which flows westward through the northern part of the commune. There is a castle on the hill overlooking the village that is occasionally open to the public.
