The 2019–20 season was SD Huesca's 60th season in existence and the club's first season back in the second division of Spanish football. In addition to the domestic league, SD Huesca 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. Following a 3–0 win over CD Numancia on 17 July 2020, Huesca won immediate promotion back to La Liga for the 2020–21 season as champions.
