This was the sixth Primeira Liga season to use video assistant referee (VAR).

Porto were the defending champions, having won their 30th title at the previous season.

Rio Ave, Casa Pia and Chaves joined as the promoted clubs from the 2021–22 Liga Portugal 2 replacing Belenenses SAD, Tondela and Moreirense, which were relegated to 2022–23 Liga Portugal 2.

As the 2022 FIFA World Cup was held between 20 November and 18 December 2022 due to the climatic conditions of the host country Qatar, the league featured an extended pause during the season.

[note 1] The relegation play-offs took place on 3 and 11 June 2023, between Marítimo, who finished 16th in the Primeira Liga, and Estrela da Amadora, who finished 3rd in Liga Portugal 2.
