2018–19 Hoofdklasse

The 2018–19 season of the Hoofdklasse was played in four leagues, two Saturday leagues and two Sunday leagues. The champions of each group promoted directly to the 2019–20 Derde Divisie. The 2018–19 Hoofdklasse started on Saturday 1 September 2018.

Promotion
In each competition teams play periods of 10 games, three times per season (30 games per season). After each period the best team which has not yet qualified earns a spot in the play-offs for the Derde Divisie as the period champion. If a period winner ends the season as champions, they will be replaced by the highest ranked team not yet qualified for the play-offs. In total 12 (substitute) period winners and 4 teams from the Derde Divisie compete for 3 spots in next seasons Derde Divisie.

Due to the removal of Papendorp from the league, there have been only 2 periods of 14 games each in the Hoofdklasse B Sunday. The highest ranked team not yet qualified for the play-offs was assigned as third period winner.

Extra match
Because JVC Cuijk, relegated from the Derde Divisie, decided to stop playing football at top amateur levels completely, due to lack of the necessary funds, an extra spot became available in the Hoofdklasse Sunday leagues. Therefore the two teams who lost in the fourth round of the play-offs were given a second chance. In an extra match, on neutral ground, these teams competed for the spot that became available.

VKW remained in the 2019-20 Eerste Klasse Sunday.
