2015 Categoría Primera B season

The 2015 Categoría Primera B season (officially known as the 2015 Torneo Águila season for sponsorship reasons) was the 26th season since its founding.

Format
16 teams competed in this Categoría Primera B season, a decrease from 18 in the last season due to the expansion of the Categoría Primera A to 20 teams starting from this season and the realization of a special promotion tournament to promote 2 additional teams to the Primera A at the start of the season. The Primera B tournament itself changed to a year-round competition with the 16 teams playing the other teams twice on a home-and-away basis and playing a regional rival twice more for a total of 32 matches. The top eight teams after the thirty-two rounds advanced to the Semifinal round where the eight teams were sorted into two groups of four and played a double Round-robin tournament group stage. Both group winners earned promotion to the Categoría Primera A and also advanced to the Final round, which consisted of two legs and decided the season winner.

Promotion tournament
The promotion tournament, which decided the two Primera B teams that would play in Categoría Primera A for its 2015 season was played from 14 to 21 January in Bogotá by DIMAYOR's eight "A-Class" associates that were in Categoría Primera B at the time. Those eight teams were split into two groups of four teams, where they played each team in their group once. Cúcuta Deportivo and Cortuluá finished on top of each group and earned promotion to the Categoría Primera A.
