2019 Campeonato Nacional Primera B
The 2019 Primera B de Chile was the 66th season of Chile's second-tier football league. The competition began on 15 February 2019 and was scheduled to end in December 2019.
Due to the 2019 Chilean protests, the competition was suspended since mid-October with three matches as well as the promotion play-offs still left. After a failed attempt to resume normal activity, on 29 November 2019, ANFP's Council of Presidents voted to conclude the season. Originally it was decided that no teams would be either promoted or relegated this season, however, on 6 December 2019 ANFP decided to declare Santiago Wanderers, who were leading the competition at the time of the suspension, as champions and promoted to the Primera División, as well as allowing another team to be promoted through a play-off. No teams were relegated to the Segunda División Profesional this season.
