Margot Betti Frank (February 16, 1926 – c. February 1945) was the elder daughter of Otto Frank and Edith Frank and the elder sister of Anne Frank. Margot's deportation order from the Gestapo hastened the Frank family into hiding. According to the diary of her younger sister, Anne, Margot kept a diary of her own, but no trace of Margot's diary has ever been found. She died in Bergen-Belsen concentration camp.
