The Torneo DIMAYOR, referred to as Torneo BetPlay Dimayor due to sponsorship by online betting company BetPlay, is the second-division football league in Colombia. The tournament was inaugurated on 29 January 1991.
DIMAYOR has applied a new format from 2015 onwards because of the expansion to 20 teams in the Primera A tournament. The league will no longer have Apertura and Finalización seasons but rather a yearlong tournament with home and away games. The first phase of the tournament is everyone against everyone home and away games. The second is a two-groups phase with the 8 top teams from the season who play each other to determine the winners of each group. The winners of the two groups are both promoted to the Primera A and play the final in home and away games to determine the champion of the season.
This is the complete list of the clubs that have taken part in the CategorÃÂa Primera B, founded in 1991, until the 2026 season. Teams who currently play are indicated in bold.
