Primera B Nacional (usually called simply Nacional B, in English National B Division) is the second division of the Argentine football league system, made up of 25 teams in the 2018–19 season.
It is played by teams from all over the country. Clubs from Buenos Aires surroundings, as well as some from Santa Fe Province, are promoted from or relegated to the Primera B Metropolitana (“Metropolitan B Division”) while for teams from the other provinces the Torneo Federal A (“Federal A Tournament”) is the next level down. In the league system of Argentine football, Nacional B is the second-highest league, and from it the three best teams are automatically promoted to Primera División.
Primera B Nacional games are often transmitted to Argentina and abroad on television by TyC Sports.
It was created in 1985 to integrate unaffiliated clubs into the Argentine football structure, which until then had only participated in Nacional championships of Argentina’s First Division tournament. It brought together teams from the old Primera B (until then, the second division) and regional leagues from several Argentine provinces.
After the 1985–86 season, the Primera B Nacional became the second hierarchical league in Argentina’s professional football, after the Primera División, and it is above the Torneo Federal A and the Primera B Metropolitana, the last one started to act as a third division for the teams directly affiliated to AFA.
For the 2016–17 season, the twenty-three participating teams played each other twice for a total of forty-six matches. Teams received three points for a win, one point for a draw, and no points for a loss. Teams are ranked by total points.
The champion and runner-up teams automatically promoted to Primera División. Six teams were relegated at the end of the season.
Torneo Federal A
The Torneo Federal A (in English “Federal A Tournament”) was founded in 2014 as a result of a change in the structure of the Argentine football league system, is one of the two leagues that form the regionalised third level of the Argentine football league system. Clubs in the Torneo Federal have indirect membership in AFA, while clubs in the Primera B Metropolitana (the other third division) have direct membership in AFA. All teams with indirect membership are from outside the city of Buenos Aires and its metropolitan area (Greater Buenos Aires), while most of the direct members are from the aforementioned area.
Primera B Metropolitana
Primera B Metropolitana is one of two professional leagues that form the third level of the Argentine football league system. The division is made up of 19 clubs mainly from the city of Buenos Aires and its metropolitan area, Greater Buenos Aires. Originally created as the second division, it became the third level after a restructuring of the system in 1985 that ended with the creation of Primera B Nacional, set as the second division since then. The other league at level three is the Torneo Federal A, where teams from regional leagues take part.
