Gioanna is an Italian feminine given name derived from the male name Giovanni, which means 'God is gracious'. It gained popularity during the Renaissance period and has been used consistently throughout Italy since then. In some cases, Gioanna may also be considered a variant spelling of Joanna, a name with Hebrew origins meaning 'God is gracious' as well.
"Gioanna was a unique baby name choice in 2007 with only five newborns sharing it that year."
