The 2024 Argentine Primera B Metropolitana is the 127th. season of the third tier of football in Argentina. The season began on 2 February and is expected to end in 14 December 2024. Twenty-two teams competed in the league.
A total of 22 teams take part of the competition, with six teams from 2023 Primera C, they are Excursionistas, Deportivo Laferrere, Ferrocarril Midland, Sportivo Italiano, Liniers y San Martín de Burzaco, plus two relegated clubs from 2023 Primera Nacional, Flandria and Villa Dálmine.
The championship was won by Colegiales, winner of Torneo Clausura, which defeated Los Andes (winner of Apertura) in a two-legged series, also promoting to 2025 Primera Nacional.[1] [2]
Primera B Metropolitana is currently organized so, during the course of a season, two round-robin tournaments are played.
The two winners play each other and the winner is recognized as the Primera B champion and is automatically promoted to Primera B Nacional.
The loser and the teams that hold the six best positions at the aggregate table have the chance to enter the Torneo Reducido (small tournament) whose winner will be promoted.
The team with the lowest aggregate points total in Primera B Metropolitana is relegated to Primera C Metropolitana.[3]
Besides, the champion and the five best placed teams will qualify to 2025 Copa Argentina.[4]
The winners of Torneo Apertura (Los Andes) and Clausura (Colegiales) played a two-legged series to decide the champions and the first team promoted to Primera Nacional.[5] The losing team entered the Torneo Reducido in the second round.
----
The teams best placed in the general table (with the exception of winners of Torneo Apertura and Clausura) qualified to "Torneo Reducido", an elimination tournament played over two legs which will define the team that will play a promotion playoff against a team from Torneo Federal A seeking promotion to Primera Nacional. Best placed teams will face worst placed teams (p.e., 1 vs 6, 2 vs 5, 3 vs 4). In the second round, the championship final loser will enter the Reducido. In case of the series ended in a tie, a penalty shoot-out will be conducted, with no extra time.
