Frankie is a pet form of Frances and Francesca, from the Latin Franciscus, which means "free one" or "from France". Once a boyish nickname, it has become a fashionable choice for girls alongside Billie and Stevie, with a cheerful vintage feel. In the United States Frankie entered the girls' top 1000 in 2015, peaked at number 539 in 2023 and ranks number 552 in 2025.
