The Médoc (; Gascon: Medòc ) is a region of France, well known as a wine growing region, located in the département of Gironde, on the left bank of the Gironde estuary, north of Bordeaux. Its name comes from (Pagus) Medullicus, or "country of the Medulli", the local Celtic tribe. The region owes its economic success mainly to the production of red wine; it is home to around 1,500 vineyards.
