The 2023–24 season of the Challenger Pro League began in August 2023 and is scheduled to end in May 2024. It is the second season under its new name after being renamed from First Division B.
This season, the league was expanded from 12 to 16 teams.
As the league expanded from 12 to 16 teams, this also involved a new format: a regular round-robin tournament of 30 matchdays. After this, the champions and runners-up will both be promoted to the 2024–25 Belgian Pro League and similarly, the two bottom finishers will be relegated to the 2024–25 Belgian National Division 1. Play-offs will be organized between the teams finishing in positions 3 through 6, with the winner of these play-offs facing the runner-up of the relegation playoffs in the 2023–24 Belgian Pro League for the final remaining ticket in the 2024–25 Belgian Pro League.
U23 are in theory eligible for promotion and relegation but always have to play at least one level below their mother club. This means that:
The table lists the positions of teams after the completion of each round, with postponed matches and points deductions only included when occurring. Teams that have played fewer matches are shown with their position underlined:
Colored cells refer to being promoted (green), in promotion play-offs (yellow) or relegation play-offs (red). Note that U23 teams are ineligible for promotion and playoffs, and the coloring is adjusted accordingly. Furthermore, if one of the mother clubs of these four teams is relegated, the U23 would automatically take up one of the relegation spots as U23 teams always have to remain at least one level below their mother club, this is not accounted for in the coloring until after the season.
The promotion/relegation play-offs were contested by the teams finishing in positions 3 to 6 in the 2023–24 Challenger Pro League, who met in a knockout tournament with both quarter-finals and semi-finals over two legs, and the highest season finisher always having home advantage in the return leg. The winner of the semi-finals played the 14th place finisher of the 2023–24 Belgian Pro League over two legs. The Belgian Pro League team had home advantage in the return leg; the winner of the final would play in the 2024–25 Belgian Pro League, with the loser playing in the 2024–25 Challenger Pro League.
Deinze won 6–1 on aggregate.
