2025 Primera Nacional
The 2025 Argentine Primera Nacional, officially known as the Campeonato de Primera Nacional Sur Finanzas 2025 for sponsorship purposes, was the 41st season of the Primera Nacional, the second-tier competition of Argentine football. Thirty-six teams competed in the league, thirty-three of which took part in the 2024 season, along with one team promoted from Torneo Federal A and two teams promoted from Primera B Metropolitana. The season began on 6 February and ended on 30 November 2025, and the fixture draw was held on 20 December 2024.
Gimnasia y Esgrima de Mendoza were the champions, winning their first title in the competition as well as achieving promotion to the AFA Liga Profesional de Fútbol after defeating Deportivo Madryn on penalties following a 1–1 draw after extra time in the championship final. The other team that promoted to the top flight at the end of the season was Estudiantes de Río Cuarto, who won the Torneo Reducido after defeating Deportivo Madryn in the finals by a 3–1 aggregate score.
Format
For this season, the competition was played under the same format as the previous season, with the thirty-six participating teams split into two zones of 18 teams, where they played against the other teams in their group twice: once at home and once away. However, since this season had two teams less than the previous one as no teams were relegated from Primera División, no interzonal matches between rival teams were played, although rival sides were still paired together for the season draw and drawn into different zones. Both zone winners played a final match on neutral ground to decide the first promoted team to the top flight for the following season, while the teams placed from second to eighth place in each zone played a knockout tournament for the second promotion berth along with the loser of the final between the zone winners. Moreover, the playoff match between the sides placing second-from-bottom in each group was not played this season, and instead four teams were relegated to the third-tier leagues, those being the bottom two teams from each zone.Similar to previous seasons, fifteen Primera Nacional teams qualified for the 2026 Copa Argentina through league performance, those being the top seven teams of each zone plus the best eighth-placed one.
