The Basque Swimming Federation (Basque: Euskal Igeriketa Erakundea, EIF; Spanish: Federación Vasca de Natación, FVN) is the body responsible for managing swimming sport in the Basque Country autonomous region.

In 1943, Maurice Larribot, as a swimmer and later a sports manager, managed to The Biscayan and Guipuzcoan swimmers end up understanding each other and come together to found the Basque Swimming Federation.

[9][10] A year later, 1944, the total unification of Basque-Navarre swimming was achieved, when Alava joined them, at the same time as the Basque Association of Referees was founded.

That same year, the Judizmendi Swimming Club settled in the Polvorin swimming pool in Alava, and organized the Basque-Navarrese "Regional" Championships there.

[12][13][14] The Basque Swimming Federation's purpose is to promote, organise and authorise swimming competitions across the Basque Country autonomous region.
