The Liga Femenina Challenge, simply known as LF Challenge, is the second division of league competition for Spanish women's basketball since the 2021–22 season.

As a single nationwide league below the top level, it is the female equivalent of the men's Primera FEB and is run by the Spanish Basketball Federation (FEB).

Each season, the top-finishing team in the LF Challenge are automatically promoted to the Liga Femenina.

The teams that finish the season in 2nd to 9th place enter a playoff tournament, with the winner also gaining promotion to the Liga Femenina.

The two lowest-finishing teams in the LF Challenge are relegated to Liga Femenina 2.
