The 2024 Primera B de Chile, also known as Campeonato Ascenso Clínicas ACHS Salud 2024 due to sponsorship by the Chilean Safety Association (ACHS),[1] was the 70th season of the Primera B de Chile, Chile's second-tier football league. The fixture for the season was announced on 24 January 2024, with the competition beginning on 23 February and ending on 7 December 2024.[2]
The competition was run under the same format used in the most recent seasons, in which the 16 participating teams played each other in a double round-robin tournament (once at home and once away) for a total of 30 matches, with the top team at the end of the 30 rounds winning the championship as well as promotion to the Campeonato Nacional for the following season. The next seven best-placed teams at the end of the regular season took part in a play-off tournament (known as Liguilla) to decide the second promoted team, with the league runners-up receiving a bye to the semi-finals. The playoffs winning team was the second and last promoted team to the top flight for the following season. The bottom-placed team at the end of the regular season was relegated to the Segunda División Profesional.[5]
