Armagnac (, French: [aʁmaɲak]) is a distinctive kind of brandy produced in the Armagnac region in Gascony, southwest France. It is distilled from wine usually made from a blend of grapes including Baco 22A, Colombard, Folle blanche and Ugni blanc, traditionally using column stills rather than the pot stills used in the production of cognac, which is made predominantly from ugni blanc grapes. The resulting spirit is then aged in oak barrels before release. Production is overseen by the Institut national de l'origine et de la qualité (INAO) and the Bureau National Interprofessionel de l'Armagnac (BNIA).

Armagnac was one of the first areas in France to begin distilling spirits, but the overall volume of production is far smaller than cognac production and therefore is less known outside Europe. In addition, it is for the most part made and sold by small producers, whereas cognac production is dominated by big-name brands, especially Courvoisier (owned by Beam Suntory), Hennessy (LVMH), Martell (Pernod Ricard), and Rémy Martin (Rémy Cointreau).
