The 2019–20 season was Deportivo de La Coruña's 113th season in existence and the club's second consecutive season in the second division of Spanish football. In addition to the domestic league, Deportivo La Coruña participated in this season's edition of the Copa del Rey. The season was slated to cover a period from 1 July 2019 to 30 June 2020. It was extended extraordinarily beyond 30 June due to the COVID-19 pandemic in Spain. In the end, Deportivo got relegated to Segunda División B in spite of seven consecutive wins in the league at the end of the autumn. The bad start and finish to the season confirmed the relegation.
