Grenache (Garnatxa negre, Grenache Noir, Garnacha, or Cannonau) is a red grape variety grown primarily for the making of wine. It grows well in hot, dry regions and is grown in southern France, Spain, South America, Australia, and California's Central Valley.

Garnacha is the Spanish name and it is certainly the most widely planted variety in Spain, and probably the world's most widely planted red wine grape. The grape was grown in Spain before it made its way to France, but the popularity of the French wines has ensured that it is now more commonly known by the French name.
