2018–19 Copa de la Reina de Fútbol

The 2018–19 Copa de la Reina de Fútbol was the 37th edition of the Spanish women's association football national cup. Real Sociedad won their first title ever.

Format changes
Since this season, all the 16 teams of the Primera División would join the competition. All the rounds were played in a single-game format.

In the round of 16, the home team was designed by the luck of the draw, while in the quarterfinals, teams that have played the previous round away had preference to host the match.

On 17 January 2019, the Royal Spanish Football Federation announced that the final will be played at Los Cármenes stadium, in Granada. For the first time in the Cup history, the Spanish royal family attended the match with Queen Letizia of Spain representing it.
