Copa del Rey 2019-20 was the 118th staging of the Copa del Rey. In its original format, the winners of the Copa del Rey were guaranteed a place in the 2020–21 UEFA Europa League group stage. However, due to the extraordinary circumstances of the COVID-19 pandemic in Spain, this spot was forfeited when the two finalists, Athletic Bilbao and Real Sociedad, chose to delay the date of the postponed final. Both teams subsequently qualified for the four-team 2020–21 Supercopa de España.
The defending champions, Valencia, were eliminated by Granada in the quarter-finals. Real Sociedad won the final 1–0 against their Basque rivals Athletic Bilbao, securing their second Copa del Rey title.
