Torneo Federal A

The Torneo Federal A (in English "Federal A Tournament") is one of the two professional leagues that form the regionalised third level of the Argentine football league system, along with Primera B Metropolitana. The competition was established in 2014 as a result of a change in the structure of the league system, replacing Torneo Argentino A.
Federal A is organised by "Consejo Federal", a division of the Argentine Football Association. Clubs in Federal A have indirect membership in AFA unlike clubs in Primera B, which have direct membership. All teams with indirect membership are from outside the city of Buenos Aires (playing in regional leagues) and its metropolitan area (Greater Buenos Aires), while most of the direct members are from the aforementioned area.
