The Copa del Rey 1914 was the 14th edition of the Copa del Rey, the Spanish football cup.
The competition started on March 29, 1914, and concluded on May 10, 1914, with the Final, held at the Estadio de Costorbe in Irun, in which Athletic Bilbao lifted the trophy for the 5th time ever with a 2–1 victory over España de Barcelona.
The Royal Spanish Football Federation took complete control of the cup tournament and decided that the clubs of the existing regional championship would qualify for the national cup championship; no free entry would be permitted anymore. Apart from some exception, the elimination rounds were played in two matches (home and away) from this season onwards.
