Marita van der Vyver (born 6 May 1958) is an Afrikaans author who has written several books for both adult and youth audiences.
In 1975, in a national Afrikaans poetry competition for matric pupils, she won a study bursary for four years at the university of her choice.
After returning to South Africa after a year of travelling in Europe, van der Vyver worked as a reporter for Die Burger, as a copywriter for Leserskring (a book club) and a feature writer for Sarie.
In 1994, Dinge van 'n Kind, another youth novel, was published before she released her first book for young children, Olinosters op die Dak in 1997.
Many of her other novels have also been adapted for stage or screen, such as Griet Skryf 'n Sprokie, Die Dinge van 'n Kind, Vergenoeg, Dis Koue Kos, Skat and Stiltetyd.
