The Campeonato de Portugal (Portuguese for "Championship of Portugal") is the fourth-level football league in the Portuguese football league system. It is a professional national league organized by the Portuguese Football Federation (FPF).
The competition began in 2013 as the Campeonato Nacional de Seniores (Seniors National Championship), replacing both the Segunda Divisão and Terceira Divisão (the third and fourth tiers of the system, respectively). On 22 October 2015, the competition was renamed the Campeonato de Portugal, its current name.
The FPF announced the creation of Liga 3 (League 3) as the new third level that will start in 2021–22, moving the Campeonato de Portugal one level lower.
The first season, 2013–14, was contested by a total of 80 clubs, which included 19 teams from the District Championships, 39 from the Segunda Divisão, 19 from the Terceira Divisão and three teams relegated from the Segunda Liga during the 2012–13 season. In 2017–18, the format consisted of five series of eighteen teams, arranged according to geographic criteria, with the exception of teams from Madeira (placed in the first series) and from the Azores (placed in the last two series). The competition played with four groups of 18 teams in 2018–19 and the curtailed 2019–20 season. It has been played with eight groups of 12 in 2020–21, then it is was reduced to five of 10 and one group of 11 teams in 2021–22 season.
