The Netherlands Football League Championship 1904–1905 was contested by eighteen teams participating in two divisions. The western division had been divided during the last two seasons, but was combined again. The national champion would be determined by a play-off featuring the winners of the eastern and western football division of the Netherlands. HVV Den Haag won this year's championship by beating PW 4-1 and 4–2.
