The 2021–22 Belgian Division 3 was the sixth season of the division in its current format, placed at the fifth-tier of football in Belgium. As the previous season was cancelled in January 2021 due to governmental measures against COVID-19 prohibiting amateur football, the division features nearly exactly the same teams.

The division consists of four separate leagues. Leagues VFV A and VFV B consist of teams with a license from the Voetbalfederatie Vlaanderen (VFV, the Flemish/Dutch speaking wing of the Belgian FA), while the leagues ACFF A and ACFF B contain 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 four leagues will be promoted to the 2022–23 Belgian Division 2.

Championship matches

Both the two VFV and two ACFF teams winning their leagues can arrange a title match to determine the overall VFV and ACFF champions of the Belgian Division 3. This season, the overall ACFF champion was decided in a single match, with Namur FLV winning the title. On VFV side, Oostkamp and Racing Mechelen decided not to play a championship match. There was hence also no match between the overall VFV and ACFF champions.

Promotion play-offs

Promotion play-offs VFV

The teams finishing in second place in the Belgian Division 3 VFV A and Belgian Division 3 VFV B take part in a promotion playoff first round together with three period winners from these both divisions. These 8 teams from the VFV play the first round of a promotion-playoff, with the four winners promoted to the 2022–23 Belgian Division 2. Losing teams will continue in rounds 2 and 3 in case extra places open up.

In division A, champions Oostkamp won all periods, meaning that in theory the teams in place 2 through 5 would qualify. 5th placed Lochristi opted however to stop playing at this level and did not take part, allowing Erpe-Mere United to take part.

In division B, second place finishers Esperanza Pelt were joined by Lille United (4th) who had won a period title. The remaining spots were taken by the highest finishers not already qualified, 3rd place Diest and 5th place Turnhout.

In Division 3 ACFF A, Manageoise, as team finishing in second place in the Belgian Division 2 ACFF A qualified for the Promotion play-offs ACFF, as well as Binche (6th overall) for winning the first period. The two other periods were won by champions Union Namur-Fosses and hence 3rd and 4th placed teams Crossing Schaerbeek and Aische were invited as well.
