List of winners of Belgian Third Division

The Belgian Third Division winners were winners of the third-highest level in Belgian football.^[1][2][3] The third division was established in 1926 with three leagues of 14 clubs each as the Promotion. In 1931, a fourth league was added. From 1948 on, a play-off is introduced to determine the Promotion champion. In 1952 the Belgian league system was changed and the Promotion became the Third Division with 2 leagues of 16 teams each. A play-off was introduced in 1993 in order to determine a third team to qualify for the second division. From 1998 on, the play-off to determine the third division champion was played no more. In 2016 the Third Division was rebranded and restructured to become Belgian First Amateur Division.
