The 2023–24 Bangladesh Championship League, also known as the ABG Bashundhara Bangladesh Championship League for sponsorship reasons, was the 12th season of the Bangladesh Championship League, Bangladesh's second-tier professional football league. The season began on 19 February 2024 and was concluded on 24 April 2024.

Brothers Union are the defending champions having won league title in the 2022–23 season.

Venue
All matches will be played at the BSSS Mostafa Kamal Stadium in Dhaka, Bangladesh

Team changes
Eight teams competed in the league: six from the previous season, one promoted from the Dhaka Senior Division Football League, and one given direct entry. Originally, Somaj Kallyan KS Mugda and Jatrabari KC were to be promoted, but both failed to obtain the professional league license. Consequently, the third-place team, PWD Sports Club, was promoted. Farashganj SC, relegated from the 2021–22 Championship League, was given direct entry after receiving a license, despite not playing in the previous Senior Division League. These two clubs replaced Swadhinata KS and Little Friends Club, who were relegated the previous year. Muktijoddha Sangsad KC and AFC Uttara, relegated from the 2022–23 Premier League, chose not to participate, with Uttara facing FIFA sanctions. Gopalganj SC was barred from returning after withdrawing from the 2023–24 Premier League despite promotion, and Fortis FC Academy withdrew due to financial constraints.
