On 23 December 2020, Porto defeated Benfica 2–0 to win the 42nd edition of the Supertaça Cândido de Oliveira, securing their first title of the season and a record-extending 22nd win in the competition.
The club's pre-season was shorter due to the late finish of the previous season (1 August 2020) caused by the COVID-19 pandemic. Porto played six matches at home against other Portuguese teams and, unlike previous seasons, there was no official presentation match.
