Club Deportivo CREF is a women's basketball team based in Madrid that currently plays in the Spanish Liga Femenina de Baloncesto.

Its women's basketball team dominated the early stages of the Spanish League, winning seven titles between 1964 and 1971, and representing Spain in the FIBA European Cup with few success.

Raimundo Saporta tried to convince Santiago Bernabéu to turn CREFF into the women's basketball section of Real Madrid, but failed in his attempt.

The club had also a men's basketball section that played in Liga EBA, but its senior team was disbanded in 2007.

However, due to the lack of support and sponsorships, the club decided to dissolve the senior team and to continue playing only in youth competitions.
