Mary Meijer-van der Sluis (11 July 1917 – 31 January 1994) was a Dutch fencer and singer.
[1] Born Mary van der Sluis to a Jewish family in Rotterdam, she married Mozes Meijer in 1940 there three months after the German bombing of that city.
Nevertheless, in 1948, when competitions were restarted, she again became Dutch champion in foil and was selected for the Olympic Games.
It was considered remarkable that a Jewish woman could compete at the Olympics so soon after the war.
In 1969, the youngest of her three children, Sophia Meijer, also became Dutch champion fencing.
