Roelof Oosthuizen (1894 –1947) was a cricketer who played one match of first-class cricket for Border in 1913. While aged 19 and a boarder at Selborne College in East London, he made his first-class debut for Border, alongside another Selbornian, Lawrence Miles, against the touring MCC in November 1913. He top-scored in Border's second innings with a hard-hitting 23. The MCC players rated him as one of the best young players in South Africa and presented him with an MCC cap. He died of heart failure at the farm in 1947, leaving a widow, Elizabeth, and a son, Ochert.
