The Franco-Cantabrian region (also Franco-Cantabric region) is a term applied in archaeology and history to refer to an area that stretches from Asturias, in northern Spain, to Aquitaine and Provence in Southern France. It includes the southern half of France and the northern strip of Spain looking at the Bay of Biscay (known as Cantabrian Sea in Spanish, hence the name).
This region shows intense homogeneity in the prehistorical record and possibly was the region of Europe with the densest population of humans during the Late Paleolithic. Vasco-Cantabria is part of the region, on the northern coast of Spain, covering similar areas to the adjacent modern regions of the Basque country and Cantabria.
