Belgian Division 1

The Belgian Division 1 is a semi-professional division and the third-highest division in the Belgian football league system, one level below the Challenger Pro League. It was created by the Royal Belgian Football Association in 2016, coming in at the third level and pushing all divisions one level down. Initially it was known as the Belgian First Amateur Division, but due to the negative connotation of the word amateur the league was renamed to Belgian National Division 1 from the 2019–20 season onwards. Then, from the 2024–25 season, a split was made into two separate divisions, with the teams holding a Flemish license and those playing with a Francophone license now playing in separate divisions within the league. The Flemish division consists of 16 teams and is referred to as the Eerste Afdeling VV, the Francophone division only contains 12 teams and is called Division 1 ACFF.
