[2] Universidad Católica were the defending champions, having won the previous tournament.
Due to the 2019 Chilean protests, the competition was suspended since mid-October with six matchdays still left.
After a failed attempt to resume normal activity that saw only one match fully played,[3] on 29 November 2019, ANFP's Council of Presidents voted to conclude the season.
Thus Universidad Católica, who were leading the competition at the time of the suspension, won their fourteenth title.
Both promoted teams replaced Deportes Temuco and San Luis, who were relegated at the end of the last season.
