Copa del Rey merupakan kompetisi piala tahunan di sepakbola Spanyol. Kompetisi ini bernama resmi Campeonato de Espana-Copa de Su Majestad el Rey, dan diselenggarakan oleh Federasi Sepakbola Spanyol, REFF.
Copa del Rey pertama kali diselenggarakan pada 1903. Ini menjadikannya sebagai kompetisi sepakbola tertua di Spanyol. Juara Copa del Rey otomatis lolos ke Europa League di musim selanjutnya. Akan tetapi, apabila juaranya sudah lolos lewat posisi di La Liga, maka posisi Europa League diberikan ke tim tertinggi di liga.
Barcelona adalah klub yang paling sukses di Copa del Rey. Pada 2018, Barca memenangi trofi keempat secara beruntun, yang menjadi trofi ke-30 mereka. Athletic Bilbao merupakan klub dengan juara terbanyak kedua.
