2012–13 Segunda Liga

The 2012–13 Segunda Liga was the 23rd season of the second-tier of football in Portugal. This season marked a series of changes in the league overall. The league's name was changed back to Segunda Liga from the previous Liga de Honra. A total of 22 teams contested the league, up from 16 in the previous season; 14 of which contested the 2011–12 season, two of which were promoted from the Portuguese Second Division (including a reserve team), one of which was relegated from the 2011–12 Primeira Liga, and five of which were new reserve teams of Primeira Liga clubs. The reserve teams were not eligible for promotion to the Primeira Liga.

Events
União de Leiria were relegated to the second division due to not fulfilling the mandatory requirements by the Portuguese League for Professional Football regarding the application process to professional competitions. Thus, Sporting Covilhã was invited to stay in the Segunda Liga despite being relegated in the previous season.

Varzim, the 2011–12 Segunda Divisão champions, also did not fulfill the requirements and were not registered in the Segunda Liga. Again, Portimonense were invited to remain in the Segunda Liga.
