The Belgian Promotion D (Vierde Klasse in Dutch) is one of the four leagues at the fourth level of the Belgian football league system, the other ones being the Belgian Promotion A, B and C. This division has existed since the 1952-53 season and is played every year with 16 clubs in each league.
The season is divided into three periods of ten matches to make a total of 30 games. The team with the most points is promoted to the Belgian Third Division as champion. The winners of each period (assuming they meet the criteria) enter the playoffs (Eindronde in Dutch) with the other nine teams from Promotion A, B and C. The 6 winners go to the second round with the sides who finished 14th in the Third Division. The 4 winners qualify for the final and the 2 winning teams play in the Third Division the following season.
Teams who finish 16th, 15th and 14th are relegated to the Belgian Provincial Leagues.
The 13th place team has to playoff in order to stay in the division.
