The 2010 Categoria Primera A season was the 63rd season of Colombia's top-flight football league. Because of new sponsorship, it was officially called the 2010 Liga Postobón season.[1]
The Assembly of DIMAYOR established a new system of competition on December 10, 2009.[2]
Apertura
The First Stage of the Apertura was a single round-robin tournament in 18 dates. The top four teams at the end of this stage advanced to the semifinals and pitted into two ties: 1 vs. 4 and 2 vs. 3. The winners of the semifinals contested the finals.
Finalización
The Finalizacion was the same as the previous season.
The Liga Postobon I was scheduled to begin on January 31, 2010.
The four qualified teams from the first stage were placed into two semifinals labelled "Semifinal A" and "Semifinal B". Each semifinal was played on a home and away basis. The teams that made up each semifinal were determined by their first stage standings: Semifinal A was between the teams that finished 1st and 4th; Semifinal B was between the teams that finished 2nd and 3rd. The team in each semifinal that finished higher in the table played the second leg at home. The winner of each semifinal advanced to the Finals.

Relegation was determined through an average of the points earn in the First Stages of the three season. For the purposes of the table, the 2009 Primera B winner (Cortuluá) entered with the same points as the team that was 16th in the beginning of the season (Real Cartagena). The team with the lowest average was relegated to the Categoría Primera B for the following season, and the team with the next lowest average played a playoff match against the 2010 Primera B runner-up.
