2025 Torneo DIMAYOR
The 2025 Torneo DIMAYOR was the 36th season of the Torneo DIMAYOR since its founding as Colombia's second division football league. The season began on 30 January and ended on 2 December 2025.
Jaguares, who won the Torneo I after defeating Patriotas in the finals, became the first team promoted to the top tier league Categoría Primera A for the 2026 season after securing a top two finish in the season's aggregate table with a 2–2 draw with Cúcuta Deportivo on 11 November 2025. The Torneo II was won by Cúcuta Deportivo, who defeated Real Cundinamarca on penalty kicks in the finals and promoted to Primera A after placing second in the season's aggregate table.
Format changes
Although the tournament kept the same format that has been used in its most recent editions, with two tournaments per season with three stages each, changes were implemented to the method of promotion of teams to Categoría Primera A for the following season. For this season, the two promoted teams were decided under the following scenarios:- If one team won both of the season's short tournaments, it earned promotion to the top flight and a two-legged promotion play-off series would be played by the next two teams in the season's aggregate table to decide the other promoted team.
- If both of the short tournament winners placed in the top two of the aggregate table at the end of the season, both teams would be promoted to Primera A and no additional stages would be played.
- If only one of the short tournament winners placed in the top two of the aggregate table, it would be promoted while the other tournament winner would play the promotion play-off against the best-placed team in the aggregate table that did not win any of the season's tournaments.
- If none of the short tournament winners ended up in the top two places of the aggregate table, both teams would play a grand final in which the winning side would be the first promoted team, and the loser of that grand final would play the aggregate table's top team in the promotion play-off for the remaining promotion berth.
Teams
Sixteen teams took part in the season. The previous season's champions Unión Magdalena and runners-up Llaneros were promoted to Primera A for the 2025 season, being replaced in Primera B for this season by Jaguares and Patriotas, who were relegated from Primera A at the end of the 2024 season after finishing in the bottom two places of the top tier's relegation table.For this season Orsomarso changed their home stadium, moving from their usual venue Estadio Francisco Rivera Escobar in Palmira to Estadio Municipal Raúl Miranda in Yumbo, Valle del Cauca Department after signing an agreement with the Yumbo Municipality to play there for one season. Although Orsomarso played most of their Torneo I home games in Yumbo, they chose to host their final match in that tournament at Estadio Daniel Villa Zapata in Barrancabermeja, aiming to get support from the city's inhabitants while also capitalizing on the local government's desire to have a professional team representing Barrancabermeja. Orsomarso eventually reached an agreement with the city's government and confirmed the relocation of their home matches to Estadio Daniel Villa Zapata starting from this season's Torneo II. The club's youth setup remained based in the Valle del Cauca Department.
