Julia the Elder (30 October 39 BCE – CE 14), known to her contemporaries as Julia Caesaris filia or Julia Augusti filia, is the daughter and only biological child of Augustus, the first emperor of the Roman Empire.

Augustus subsequently adopts several male members of his close family as sons.

Julia resulted from Augustus' second marriage with Scribonia, her birth occurring on the same day as Scribonia's divorce from Augustus, who wished to marry Livia Drusilla.

She is the daughter of the Emperor Augustus, stepsister and second wife of the Emperor Tiberius, maternal grandmother of the Emperor Caligula and the Empress Agrippina the Younger, grandmother-in-law of the Emperor Claudius, and maternal great-grandmother of the Emperor Nero.
