The 1913 Copa del Rey comprised two different competitions held the same year.

Due to disagreements between the Federación Española de Clubs de Football (FECF), forerunner of the Royal Spanish Football Federation (Spanish: Real Federación Española de Fútbol, RFEF) and some clubs, in 1913 two parallel competitions were held: an "official", organized by the FECF (Federación Española de Clubs de Football), in Madrid and an "unofficial", organized by the UECF (Unión Española de Clubes de Fútbol), in Barcelona.

The competition started on 16 March 1913 and concluded on 23 March 1913 with the replay of the final (FEF), held at the O'Donell, Madrid, in which Racing de Irún lifted the trophy for the first time ever with a 1–0 victory over Athletic Bilbao, with the only goal of the match being scored by Manuel Retegui.

Both legs ended in draws (2–2 and 0–0), thus forcing a play-off in which Barça lifted the trophy with a 2–1, thanks to first-half goals from José Berdié and Apolinario Rodríguez.
