The Netherlands Football League Championship 1902–1903 was contested by eighteen teams participating in three divisions. This season, the western division had been split in two, creating the Eerste Klasse West-A and the Eerste Klasse West-B. The national champion would be determined by a play-off featuring the winners of the three divisions of the Netherlands. HVV Den Haag won this year's championship by beating Vitesse Arnhem and Volharding.
