Julie is the French form of Julia, the feminine of the Roman family name Julius, usually explained as "youthful" or "downy-bearded" and linked by legend to Jupiter. Actress Julie Andrews of Mary Poppins and The Sound of Music made it one of the sweetest-sounding names of mid-century America, when it was a top 50 name. Julie was number 190 in 2000 and has gradually slipped to number 873 among girls in 2025.
