Johannes Leonardus "Jan" Flinterman (2 October 1919 – 26 December 1992) was a Dutch Royal Air Force pilot during World War II[1] and a racing driver.

Together with Dries van der Lof, he was the first driver from the Netherlands to compete in Formula One.

When he had to retire his Maserati with a failure of the rear axle, he was able to take over the similar car of his team mate, Chico Landi.

Flinterman finished the race in ninth place, scoring no championship points.
