The Primera División is the premier professional futsal league in Spain.

Administered by Liga Nacional de Fútbol Sala, it is contested by 16 teams and is played under UEFA rules.

This means that in Liga Nacional de Futbol Sala the league ends after every team plays 30 matches.

Like many other leagues in continental Europe, the Liga Nacional de Futbol Sala takes a winter break once each team has played half its schedule.

One unusual feature of the league is that the two halves of the season are played in the same order—that is, the order of each team's first-half fixtures is repeated in the second half of the season, with the only difference being the stadiums used.
