Jianna is an American spelling of Gianna, the Italian short form of Giovanna, meaning "God is gracious". The J spelling makes the hard G sound clear to English speakers and follows Gianna's big rise in the 2000s and 2010s. Jianna peaked at number 769 in 2021, slipped out of the US top 1000 briefly in 2023 and stands at number 973 among girls' names in 2025.
