The short answer
Julia is the feminine form of the Roman family name Julius. Behind the Name says Julius "was possibly derived from Greek ἴουλος (ioulos) meaning 'downy-bearded'", or may be related to the god Jupiter, so the meaning is uncertain even though the lineage is not. The name was borne by women of the imperial family, including Julia Augusta (Livia Drusilla), wife of Augustus, and Julia the Elder, his daughter; it is briefly mentioned in the New Testament and belonged to several early saints. In English it is said JOO-lee-ə. Parents choose it as a classic that works across many languages. It ranked #131 for girls in the United States in 2025.
Meaning and etymology
Behind the Name gives Julia as the "feminine form of the Roman family name Julius". That family name, per the Julius entry, "was possibly derived from Greek ἴουλος (ioulos) meaning 'downy-bearded'. Alternatively, it could be related to the name of the Roman god Jupiter." The Julia entry records notable Roman bearers, Julia Augusta (also known as Livia Drusilla), the wife of Emperor Augustus, and Julia the Elder, daughter of Augustus and wife of Tiberius, and notes that "a person by this name has a brief mention in the New Testament", that the name "was also borne by a few early saints and martyrs, including the patron saint of Corsica", and that Shakespeare used it in The Two Gentlemen of Verona (1594). Behind the Name adds that Julia "has been common as a given name in the English-speaking world only since the 18th century", and names the actress Julia Roberts (born 1967) as a famous modern bearer. Confidence is marked "likely" because the derivation from Julius is certain while the meaning of Julius is offered only as a possibility.
