The 2019–20 season was Real Valladolid's 89th season in existence and the club's second consecutive season in the top flight of Spanish football and the 43rd season in La Liga. In addition to the domestic league, Valladolid 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.
