The 2018–19 Belgian Second Amateur Division is the third season of the division in its current format, placed at the fourth-tier of football in Belgium. The division consists of three separate leagues, each containing 16 teams. Leagues A and B consist of teams with a license from the Voetbalfederatie Vlaanderen (VFV, the Flemish/Dutch speaking wing of the Belgian FA), while league C contains teams with a license from the Association des Clubs Francophones de Football (ACFF, the French speaking wing of the RBFA). The champions from each of the three leagues will promote to the 2019–20 Belgian First Amateur Division. The fixtures were announced in July 2018.
