Giana is a shortened spelling of Gianna, the Italian pet form of Giovanna, the feminine of John, which comes from Hebrew and means "God is gracious". With one n the name reads a little lighter and is often pronounced with a long a, like Jana. Giana entered the US top 1000 in 2002, peaked at number 568 in 2010 and has bounced between the 700s and 900s since, ranking 921st in 2025.
