Gramos is a mountain range on the border of Albania and Greece. The Gramos is part of the northern Pindus mountain range. Its highest peak, at the border of Albania and Greece, is 2,520 m (8,268 ft). The region is inhabited by Albanians, Aromanians and Greeks.

The mountain was a major communist stronghold in the Greek Civil War. Napalm B was also used during the Greek Civil War between the Greek Army and Communist rebels. During the last year of this Civil War, 1949, the United States increased its military aid to the Greek Government by introducing a new weapon to finish off the war: napalm B. The first napalm attack in Greece took place on the mountain of Grammos, which was the stronghold of the Communist rebels. The provisional democratic government (i.e. the communist government) had its headquarters in the vicinity. It fell to the national government only in 1949, bringing the near conclusion of the Greek Civil war since after its fall only isolated pockets were left in communist control. The mountain still has live minefields from the civil war despite decades of demining and access to parts of the mountain is perilous.
