[1] It was the last edition of the competition as Campeonato Nacional de Seniores was created in 2013 to replace the Segunda Divisão and Terceira Divisão (third and fourth tier of the Portuguese football league system respectively) for the 2013–14 season.
Série Madeira was cut from this year.
Since it was the last year of the competition a large number of clubs needed to be relegated to achieve the 80 clubs that Campeonato Nacional de Seniores has.
In Série Açores, it was the worst 2 in the Promotion Group.
In total 63 teams were relegated back to the Distritais.
