Julia Flavia (born sometime between 64 and 67, died 91) was the only child of Titus Flavius Vespasianus (the future Emperor Titus). Her mother was Marcia Furnilla. She was married once, presumably to a man from gens Julia. In the year 84, her uncle, the Emperor Domitian (who had just divorced the previous year) became obsessed with her, forced her to divorce her husband, and made Flavia his mistress. She became pregnant at least once, and died in 91 during an abortion.
