The Basques are a Southwestern European ethnic group, characterised by the Basque language, a common culture and shared genetic ancestry to the ancient Vascones and Aquitanians. Basques are indigenous to, and primarily inhabit, an area traditionally known as the Basque Country —a region that is located around the western end of the Pyrenees on the coast of the Bay of Biscay and straddles parts of north-central Spain and south-western France.

Basque is the only surviving Paleo-European language spoken in Europe, predating the arrival of speakers of the Indo-European languages that dominate the continent today. Basque is spoken by the Basques and other residents of the Basque Country, a region that straddles the westernmost Pyrenees in adjacent parts of northern Spain and southwestern France. Basque is classified as a language isolate, with no relationship to any other language having been established. The Basques are indigenous to and primarily inhabit the Basque Country. The Basque language is spoken by 806,000 Basques in all territories. Of these, 93.7% (756,000) are in the Spanish area of the Basque Country and the remaining 6.3% (50,000) are in the French portion.
