Athletic Club Femenino is the women's football section of Athletic Bilbao, competing in Liga F. Athletic is one of the most successful women's teams in Spain, with five championships.

The team plays at the club's facilities in Lezama on the outskirts of Bilbao.

Athletic Club, commonly known as just Athletic domestically and often as Athletic Bilbao abroad, is a professional football club based in the city of Bilbao in the Basque Country, Spain. They are known as Los Leones because their stadium was built near a church called San Mamés, which was named after Saint Mammes, an early Christian thrown to the lions by the Romans. Mammes pacified the lions and was later made a saint. The team plays its home matches at the San Mamés Stadium. Its home colours are red and white-striped shirts with black shorts.
