# 2021 Primera B de Chile

The 2021 Primera B de Chile, also known as Campeonato Ascenso Betsson 2021 for sponsorship purposes, was the 67th season of the Primera B de Chile, Chile's second-tier football league. The season started on 3 April 2021.
Coquimbo Unido were the champions, winning their fourth title in the competition as well as clinching promotion to Primera División with a 2–1 victory over Fernandez Vial on 13 November, the last matchday of the regular season.

## Format

The tournament was played by 16 teams, 12 returning from the previous season, three relegated from Campeonato Nacional (Coquimbo Unido, Deportes Iquique and Universidad de Concepción), and the Segunda División Profesional champions. The 16 teams play each other in a double round-robin tournament (once at home and once away) for a total of 30 matches. The top team at the end of the 30 rounds was the champion and was promoted to the Campeonato Nacional for its 2022 season, with the next four teams playing a play-off stage with its winner qualifying for a promotion/relegation play-off against the 15th-placed team of the Campeonato Nacional. On the other hand, the bottom-placed team of the table was relegated to the Segunda División Profesional.

## Teams

Originally, Lautaro de Buin were to take part in the competition as 2020 Segunda División Profesional champions, but the club was suspended per ruling by ANFP's Court of Justice due to irregularities with the contracts of their players, and later expelled from the ANFP on 5 May 2021. Following an appeal by Lautaro de Buin, on 10 June 2021 the original ruling was changed to a six-point deduction in the Segunda División standings, thereby losing the first place and declaring Fernandez Vial as Segunda División champions, who in turn also took Lautaro's place in Primera B.
