The Liga Femenina de Baloncesto, also known as Liga Femenina Endesa for sponsorship reasons, is the highest level of league competition for women's basketball in Spain.

It is the women's equivalent of the men's Liga ACB and is run by the Spanish Basketball Federation.

Throughout its history 13 clubs have been champions; CB Godella-Pool Getafe (with both names), Ros Casares and Perfumerías Avenida have won the most championships, with eight.

This means that in Liga Femenina de Baloncesto the league's regular season ends after all teams play 26 matches.

Each season, the two last qualified teams of the regular season are relegated to Liga Femenina 2 de Baloncesto and replaced by the two first qualified teams of this league.
