2021 Supercopa de España

The 2021 Supercopa de España was the 37th edition of the Supercopa de España, an annual football competition for clubs in the Spanish football league system that were successful in its major competitions in the preceding season.

It was the second straight edition played under the new format with four teams. They included 2019–20 Copa del Rey winners Real Sociedad, 2019–20 La Liga winners Real Madrid, 2019–20 Copa del Rey runners-up Athletic Bilbao and 2019–20 La Liga runners-up Barcelona. The competition was initially supposed to be held in Saudi Arabia like the previous year, but restrictions related to the global COVID-19 pandemic forced it to remain in Spain. The semi-finals took place in the cities of Córdoba and Málaga, on 13 and 14 January 2021. The final was played at Estadio de La Cartuja in Seville on 17 January 2021.

Athletic Bilbao won the tournament for their third Supercopa de España title.

Draw
The draw took place on 17 December 2020 at the Royal Spanish Football Federation headquarters, in La Ciudad del Fútbol.
