Athletic Club Femenino B is a Spanish women's association football team based in Bilbao, in the autonomous community of the Basque Country, Spain.
Founded in 2002, it is the reserve team of Athletic Club Femenino, and currently plays in the Primera Federación, playing their home matches at the Lezama Facilities.
Reserve teams in Spain play in the same league system as the senior team, rather than in a reserve team league. They must play at least one level below their main side, and thus Athletic B are ineligible for promotion to the Primera División and cannot play in the Copa de la Reina.
