A focused population profile of French Basques, their western Pyrenean background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
French Basques are Basques from the northern Basque Country in southwestern France, especially Labourd, Lower Navarre, and Soule. Their history is tied to the western Pyrenees, Atlantic valleys, pastoral communities, coastal trade, cross-border Basque identity, and the broader French Basque region.
Basque, or Euskara, is a language isolate, while French is widely used in public life. French Basque identity is related to Spanish Basque identity but has its own regional and national context.
As a genetic reference, Basque France is useful for comparison with Soule, Lower Navarre, Labourd, Basque Spain, Alava, Biscay, Gipuzkoa, Navarre, Bearn, Landes, and other western Pyrenean references.
In the World Genetics modern G25 comparison, Basque France is closest to Basque France Soule, Basque France Lower Navarre, Basque Spain Alava, Basque France Labourd, Basque Spain Navarre Roncal, Basque Spain Biscay, Basque Spain, Basque Spain Navarre Northwest, Basque Spain Gipuzkoa Southwest, and Basque Spain Gipuzkoa Tolosa. The result forms a tight Basque and western Pyrenean cluster across the French-Spanish border.
| Population | Distance |

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. French Basque is best interpreted as a western Pyrenean Basque profile, with Soule, Lower Navarre, Labourd, Alava, Biscay, Navarre, and Gipuzkoa references close.
The heatmap should emphasize the French Basque Country, Labourd, Lower Navarre, Soule, the Spanish Basque Country, Navarre, Alava, Biscay, Gipuzkoa, and the western Pyrenees.
Yes. Spanish Basque regional references, including Alava, Biscay, Navarre, and Gipuzkoa, appear close to Basque France.
Basque France sits in a tight Basque and western Pyrenean cluster, with Basque regional references dominating the closest-match list.
Soule, Lower Navarre, and Labourd are the closest French Basque regional references in this table.
