The 1993 Categoría Primera A season, known as 1993 Copa Mustang for sponsorship purposes, was the forty-sixth season of Colombia's top-flight football league. Junior won the league for the third time after winning the final quadrangular, clinching the title after defeating América de Cali 3–2 in their final match.
América de Cali were the defending champions, but placed last in the final quadrangular.
Format.
The season was split into four parts: Torneo Apertura, Torneo Finalización, semifinal quadrangulars, and final quadrangular. In the Torneo Apertura, the 16 participating teams were divided into two groups of eight, in which teams played each of their group rivals twice for a total of 14 matches, while in the Torneo Finalización, the 16 teams played each other twice in a double round-robin tournament for a total of 30 matches. The results of both the Apertura and the Finalización were combined into an aggregate table ("Reclasificación"), with the top eight teams in that table at the end of the season's 44 rounds advancing to the semifinal quadrangulars. Bonus points for the final stages (semifinal and final quadrangulars) were awarded at the end of the Apertura and Finalización tournaments to the top four teams of each tournament, with the following scale being used: 1.00, 0.75, 0.50, and 0.25. The placements of the top four teams in the Apertura for the purposes of bonus allocation were decided by two-legged playoffs between the group winners and runners-up.
In the semifinal quadrangulars, the eight participating teams were divided into two groups of four in which they played each of their group rivals twice, with the top two teams of each group advancing to the final quadrangular, in which they again played their other group rivals twice. The team that topped the final quadrangular was the champion.
