Johannes Leonardus "Jan" Flinterman (born 2 October 1919 in The Hague, died 26 December 1992 in Leiden) was a Dutch racing driver. A distinguished air force pilot during the Second World War, Flinterman later turned to motorsport. With Dries van der Lof, he was one of two Dutch drivers competing in the early days of Formula 1, although both would have very different fates. While van der Lof became one of the best drivers of his time, Flinterman struck a partnership with Jacques Swaters, driving his cars in the Dutch Grand Prix from 1951.
In a rare race abroad, Flinterman was gravely injured in an accident in the 1954 Syracuse Grand Prix in which he broke all four limbs, fractured his skull and sustained internal injuries. Flinterman never raced again, and upon recovery, he became a board member for a Dutch air company.
