The Derde Divisie, formerly known as Topklasse, is the fourth tier of football in the Netherlands, which had its inaugural season as a third tier in 2010–11 and as a fourth tier in 2016–17. The league is placed between the Tweede Divisie and the Hoofdklasse, the third and fifth tiers of Dutch football, respectively. The introduction of the then Topklasse resulted from discussions between the Royal Dutch Football Association, the Coöperatie Eerste Divisie and the Centraal Overleg Hoofdklassers.
