Derde Divisie 2016–17

The 2016–17 Derde Divisie season is the first edition of the new Dutch fourth tier, formerly called Topklasse, since the restructuring of the league system in the summer of 2016.

This change in the league system was approved in a KNVB assembly in December 2014.

A new semi-professional level Tweede Divisie was added at the third tier, thus the Topklasse and leagues below it decremented by one level, and furthermore, promotion and relegation between the Tweede Divisie and the new Derde Divisie became mandatory.
