2018 Chilean Primera División

The 2018 Campeonato Nacional, known as Campeonato Nacional Scotiabank 2018 for sponsorship purposes, was the 88th season of top-flight football in Chile. The season started on 2 February and ended on 2 December. Colo-Colo were the defending champions, having won the 2017 Transición tournament. Universidad Católica won their thirteenth title on the last day of the season following a 2–1 win at Deportes Temuco, who were relegated to the second tier with this defeat.

Format changes
For the 2018 season, the Asociación Nacional de Fútbol Profesional (ANFP) approved a change of format from the Apertura-Clausura system that had been used in previous seasons, to a single tournament during the calendar year. The 16 teams played each other twice (once at home and once away) for a total of 30 matches. Qualification for the Copa Libertadores and Copa Sudamericana was awarded to the top seven teams at the end of the season, as well as the Copa Chile champions, while the bottom two teams were automatically relegated.
