The season started on 1 February and ended on 20 December 1998. Deportivo Cali were the champions, clinching their seventh domestic league title after beating Once Caldas in the finals.
América de Cali were the defending champions, but placed third in their semifinal group and thus failed to qualify for the final stage of the competition.
