Armagnac ( ) is a distinctive kind of brandy or eau de vie, made of mainly the same grapes as cognac and undergoing the same aging in oak barrels, but mainly with column still distillation (cognac and part of armagnac is distilled in pot stills). Armagnac production is overseen by INAO and the Bureau National Interprofessionel de l'Armagnac (BNIA).

Along with cognac in Cognac, France and sherry in Jerez, Spain, it is one of only three officially demarcated brandy regions in Europe.

Armagnac is one of two rivals for cognac wine recognition as the finest producer of eau de vie (brandy) in the world. Its name comes from the Armagnac region of France where it originates.

Its quantity of production is significantly lower than that of the Cognac region; for every six bottles of Armagnac sold around the world there are one hundred bottles of cognac sold.

Armagnac has been making brandy for around 200 years longer than Cognac.
