Colombia crowns two champions every year, and 2025 was a good example of how that works. Santa Fe won the Apertura by beating Independiente Medellín 2-1 on aggregate, then Junior won the Finalización with a 4-0 aggregate victory over Deportes Tolima.
That double-champion system is one of the first things people notice about the Categoría Primera A. This guide covers how the league runs, who the biggest clubs are, the players it has produced and the derbies that define it.
Key Takeaways
- The league was founded in 1948 and has 20 clubs, with two separate tournaments each year, the Apertura and the Finalización.
- Atlético Nacional lead the all-time list with 18 titles, ahead of Millonarios on 16 and América de Cali on 15.
- Relegation is decided by a three-year points average, and the bottom two clubs drop to the Categoría Primera B.
- The league has produced players such as Juan Cuadrado, and it gave James Rodríguez and Radamel Falcao their start in Colombian football.
How the League Works
The Categoría Primera A runs under DIMAYOR and has 20 clubs. Since 2002, each season has been split into two independent championships: the Apertura, which runs from February to June, and the Finalización, which runs from July to December. Both follow the same three-stage format.
- First stage. Each club plays every other club once, a 19-match round-robin.
- Semi-final groups. The top eight split into two groups of four, known as cuadrangulares, and play each other home and away.
- Final. The two group winners meet in a two-legged final.
Relegation works separately. The bottom two clubs drop each year based on a three-year average of first-stage points, and the top two from the Primera B come up. In 2025, the average was taken across the 2023, 2024 and 2025 seasons, and Envigado (0.847) and Unión Magdalena (0.800) went down.
The Biggest Clubs
| Club | City | League Titles | Notable |
|---|---|---|---|
| Atlético Nacional | Medellín | 18 | Copa Libertadores winners in 1989 and 2016 |
| Millonarios | Bogotá | 16 | The Ballet Azul side of the 1950s |
| América de Cali | Cali | 15 | Four Libertadores finals, relegated in 2011 and back in 2017 |
| Junior | Barranquilla | 11 | Finalización 2025 winners |
| Santa Fe | Bogotá | 10 | Apertura 2025 winners |
Sixteen different clubs have won the title since 1948, so the table covers only the most successful. Millonarios won their 16th league title in the 2023 Apertura and followed it with the 2024 Superliga Colombiana.
Atlético Nacional play at the Atanasio Girardot Stadium, which holds around 44,800, and they are called Los Verdolagas, after the green and white of the Antioquia flag. They won their 2024-II league title and added more Copa Colombia trophies in 2023, 2024 and 2025.
The El Dorado Era
Colombian football had one of its great eras between 1949 and 1954, when FIFA sanctions allowed clubs to sign foreign players freely. Millonarios used that window to build the Ballet Azul, a team of stars from Argentina and elsewhere, and Alfredo Di Stéfano played for them from 1949 to 1953. Millonarios won the league in 1949, 1951, 1952 and 1953 during that stretch.
Libertadores Memories
Atlético Nacional’s two Libertadores titles, in 1989 and 2016, are the stand-out continental results. They also won the Copa Interamericana in 1989 and 1995 and the 2017 Recopa Sudamericana. América de Cali came closest to a Libertadores of their own, losing four finals, including 1987, when a draw against Peñarol would have been enough.
For 2026, Colombian clubs entered the Copa Libertadores through the 2025 results: Santa Fe, Junior, Deportes Tolima and Independiente Medellín, plus the top two non-champion clubs in the aggregate table. Atlético Nacional, América de Cali, Atlético Bucaramanga and Millonarios took Copa Sudamericana places.
A Talent Pipeline
Colombian football has a long record of selling players to Europe, though the starting points vary.
- Juan Cuadrado is the clearest Primera A graduate. He debuted for Independiente Medellín in 2008, played 30 league games over two seasons and signed for Udinese on 2 July 2009.
- James Rodríguez started at Envigado in 2006 at 14, helped the club to the 2007 Primera B title and moved to Banfield in 2008. He joined Porto for €5.1 million in 2010 and won the Golden Boot at the 2014 World Cup with six goals before a €63 million move to Real Madrid.
- Radamel Falcao made his debut at 13 for Lanceros Boyacá in the second division in 1999, then developed at River Plate. He returned to Colombia with Millonarios in 2024 and has 36 goals for the national team, a record.

The Derbies
Colombian football’s biggest games come in city derbies. The Clásico Paisa pits Atlético Nacional against Independiente Medellín.
The Clásico Capitalino between Millonarios and Santa Fe has been played every season since 1948, with Millonarios ahead overall. The Clásico Vallecaucano between América de Cali and Deportivo Cali dates back to 1931, and it regularly draws 30,000 to 35,000 fans.
Nacional’s matches against Millonarios and América de Cali are also billed as superclásicos.
Difficult Chapters
The league has had hard moments. The 1989 championship is the only one that was not awarded, after a referee was assassinated. América de Cali’s 2011 relegation, the first in their history, showed that even the biggest clubs are not safe, and they needed the 2016 Primera B title to come back.

Why the Primera A Keeps Producing Stories
Two champions a year, a deep derby culture and a steady stream of players heading for Europe give the league plenty to follow. It also resets every six months, so a poor first half does not end a season.
If you are new to it, start with the cuadrangulares, where the eight best clubs from the first stage settle each championship.
