World War II in the Basque Country refers to the period extending from 1940 to 1945. It affected the French Basque Country, but also bordering areas across the Pyrenees on account of the instability following the end of the Spanish Civil War, and the friendly ties between Germany, Vichy France, and the triumphant Spanish military dictatorship.

Gurs internment camp was an internment camp and prisoner of war camp constructed in 1939 in Gurs, a site in southwestern France, not far from Pau. The camp was originally set up by the French government after the fall of Catalonia at the end of the Spanish Civil War to control those who fled Spain out of fear of retaliation from Francisco Franco's regime. At the start of World War II, the French government interned 4,000 German Jews as "enemy aliens", along with French socialist political leaders and those who opposed the war with Germany.
