2023 Categoría Primera B season

The second promotion spot to Primera A for the 2024 season would be decided in a promotion play-off between the Grand Final loser and the best-placed team of the season's aggregate table, other than the Grand Final winners.

The previous season's champions Boyacá Chicó and the winners of the promotion play-off series Atlético Huila were promoted to Primera A for the 2023 season and were replaced in Primera B by Patriotas and Cortuluá, who were relegated from Primera A at the end of the 2022 season after finishing in the bottom two places of the top tier's relegation table.

[4] On 14 December 2022 the General Assembly of DIMAYOR approved a proposal by Cortuluá to move their home matches from Tuluá to Yumbo, Valle del Cauca Department, starting from this season.

[5] On 22 June 2023, and motivated by the lack of support from both the government and local private enterprises, the board of Valledupar voted 4–1 to move the club to Soacha and rebrand it, effectively folding the existing club.

The move was confirmed at a General Assembly of DIMAYOR on 6 July 2023,[6] in which Real Soacha Cundinamarca was announced as the new club that replaced Valledupar for the second half of the season.
