Fatima Jinnah (31 July 1893 – 9 July 1967) was a Pakistani politician, stateswoman, author, and activist. She was the younger sister of Muhammad Ali Jinnah, the founder and first governor-general of Pakistan.
After obtaining a dental degree from the University of Calcutta in 1923, she became the first female dentist in undivided India. She was a close associate and adviser to her brother, Muhammad Ali Jinnah. After the independence of Pakistan, she co-founded the All Pakistan Women's Association, which played an integral role in the settlement of women migrants in the newly formed country. She remained the closest confidant of her brother until his death. After his death, Fatima was prevented from addressing the nation until 1951; her 1951 radio address was interrupted, which many believed was an attempt by the Liaquat administration to censor her. She wrote the book My Brother in 1955, but it was only published 32 years later, in 1987.
