1989–90 Liga Nacional de Fútbol Femenino

The 1989–90 Liga Nacional de Fútbol Femenino was the second season of the Spanish women's football top tier. Atlético Villa de Madrid won their first title ever.

The season did not use a regular relegation system. With the expansion of the league, all teams entering for the 1990–91 season were placed into a group stage. The eight best teams from this preliminary round, regardless of placement in the 1989–90 season (or non-placement in the case of new entrants), went on to play in the 1990–91 División de Honor, recognised as the top tier. The rest of the teams contested a league split into groups and still called the Liga Nacional Primera División, considered the second tier.
