The 2025 Categoría Primera A season (officially known as the 2025 Liga BetPlay Dimayor season for sponsorship purposes) will be the 78th season of the Categoría Primera A, Colombia's top-flight football league. The season is scheduled to begin on 23 January and end on 14 December 2025.[1]
Two tournaments (Apertura and Finalización) will be played in the season, each one of them being an independent championship. Atlético Nacional will enter the season as defending champions, having won the 2024 Finalización tournament.
Format
The competition format for this season was approved by the Extraordinary Assembly of DIMAYOR held on 16 December 2024, which decided to keep the same system used in the previous seasons, with two tournaments (Apertura and Finalización) of three stages each: a first stage in which the 20 teams play each other once (with an additional match against a regional rival and reversed fixtures for the Finalización tournament), a semi-final stage (cuadrangulares) played by the top eight teams from the previous stage in which the eight teams are split into two groups of four and the top two teams from the first stage will be seeded in different groups, and a double-legged final series played by the winners of both semi-final groups.[2]
For this season, the regional derbies matchday in the first stage of each tournament was reinstated after being scrapped in 2024 due to scheduling constraints, whilst the distribution of international berths was kept: both season champions as well as the top two non-champion teams in the aggregate table will qualify for the Copa Libertadores, with the next best three teams in the aggregate table as well as the Copa Colombia champions qualifying for the Copa Sudamericana.[1]
20 teams will take part in the season, the top 18 teams in the relegation table of the previous season as well as the 2024 Primera B champions Unión Magdalena and runners-up Llaneros. Both teams clinched promotion on 14 December 2024, following the 2024 Primera B's Grand Final.[3] The promoted teams will replace Jaguares and Patriotas, the bottom two teams in the relegation table of the 2024 season, who were relegated to Primera B after nine and one year in the top flight, respectively.[4]
The Torneo Apertura (officially known as Liga BetPlay Dimayor 2025–I) will be the first tournament of the 2025 season. It is scheduled to begin on 23 January and end on 28 June 2024.[1]

Relegation
A separate table is kept to determine the teams that are relegated to the Categoría Primera B for the next season. This table is elaborated from a sum of all first stage games played in the three most recent seasons (including the 2023–I, 2023–II, 2024–I, 2024–II, 2025–I, and 2025–II tournaments), with the points earned being averaged per match played. The bottom two teams of the relegation table at the end of the season will be relegated to Categoría Primera B.
