The 2019–20 season was Real Sociedad's 73rd season (and the 10th consecutive) in La Liga, the top flight of Spanish football. In addition to the domestic league, Real Sociedad participates 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.
