2020–21 Primeira Liga
The 2020–21 Primeira Liga (also known as Liga NOS for sponsorship reasons) was the 87th season of the Primeira Liga, the top professional league for Portuguese association football clubs. The season started later than usual, on 18 September 2020, due to the delayed end of the previous season caused by the COVID-19 pandemic, and it concluded on 19 May 2021. 

This was the fourth Primeira Liga season to use video assistant referee (VAR). As was the case at the end of the previous season, there were limited or no attendance in the stadiums besides each team's staff and personnel.

Porto were the defending champions. On 11 May 2021, Sporting CP secured a 19th title after a 1–0 home win against Boavista, their first title since the 2001–02 season.
