Torneo Argentino B was one of two leagues that form the fourth level of the Argentine football league system, made up of 100+ teams playing within eight regional zones across Argentina.
The other league at level four was – and still is – the Primera C Metropolitana, which is a competition for the numerous clubs in the city of Buenos Aires and the Greater Buenos Aires metropolitan area.
The Torneo Argentino B season would end with the top teams from each zone playing in cross-over playoffs, culminating with overall champions and a number of teams (varied by season) eligible for promotion to the following season's Torneo Argentino A competition.
The Torneo Argentino B was replaced with the similar Torneo Federal B for the 2014–15 season (itself reorganized as the nine zone Torneo Regional Federal Amateur for the 2018–19 season ), while the Primera C continued on as its tier four companion for the Buenos Aires area.
