Portugal - Campeonato Nacional - Damer

One of the first women's football national championship in Portugal began in 1985, under the title Taça Nacional. It included all clubs interested in participating and comprised two stages, in the first stage clubs were divided in different zone groups with the top clubs from each zone advancing to the second stage to decide the champion. Boavista dominated this competition, winning all its eight editions. The competition was renamed Campeonato Nacional for the 1993–94 season though keeping the same format. On the 1998–99 season, more matches were added to the competition as clubs not advancing to the championship stage played would play again between them. In 2001, the UEFA Women's Cup was created with the previous season winners of this competition qualifying to play on it. The Portuguese cup started on the 2003–04 season with all clubs competing on it.

In 2005, the Campeonato Nacional II Divisão was created, leaving only the top 6 teams on the first tier, each one playing the others 4 times with the bottom team being relegated. The competition was expanded for the 2009–10 season to 10 teams, playing each other twice, with top clubs advancing to a championship group and bottom teams to a relegation group. A supercup, played between the championship winners and cup winners, started in 2015.

For the 2016–17, the Portuguese Football Federation granted direct entrance to the first tier to four Primeira Liga teams, with Sporting CP, Braga, Estoril and CF Os Belenenses taking the spots. This teams had to keep the women's team for at least three seasons and introduce Under-19 sides to promote youth football. This way, Sporting CP and Braga became the first professional women's football teams in Portugal. That same season, the format was reverted to a single stage, where the 14 teams (reduced to 12 on the following season) play each other twice. The league cup was introduced for the 2019–20 season with teams qualifying through mid-season standings on the championship. That season was interrupted due to the COVID-19 pandemic in Portugal with no title awarded and no teams relegated. This was the first time no title was awarded since the creation of the competition. This led to a total of 20 teams on the first tier on the following season, requiring a format change for that season, with a first stage where teams are divided in two groups playing each other once with top teams advancing to a championship group and bottom teams to relegation groups.
