1939–40 Netherlands Football League Championship

The Netherlands Football League Championship 1939–1940 was contested by 52 teams participating in five divisions. The national champion would be determined by a play-off featuring the winners of the eastern, northern, southern and two western football divisions of the Netherlands. Feijenoord won this year's championship by beating Blauw-Wit Amsterdam, Heracles, Juliana and GVAV Rapiditas.

This season's championship was not considered official. Owing to the start of World War II, not all teams played an equal number of matches.
