A total of 18 teams contest the league, including 14 sides from the
2019–20 season, 2 teams relegated from the
2019–20 Primeira Liga and 2 promoted from the
2019–20 Campeonato de Portugal.
Vitória de Setúbal and
Desportivo das Aves (16th and 18th placed teams in
2019–20 Primeira Liga) were punished by the
Portuguese Professional Football League for failing to produce valid licensing documentation with direct relegation to
2020–21 Campeonato de Portugal and, because of that,
Cova da Piedade and
Casa Pia (17th and 18th placed teams in
2019–20 LigaPro) were not relegated.
