Belgian National Division 1

The Belgian National Division 1, commonly referred to as simply Eerste Nationale in Dutch or Nationale 1 in French, is a semi-professional 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. Until the 2019–20 season, it was known as the Belgian First Amateur Division, but was renamed due to the negative connotation of the word amateur.
