Luana has two separate sources: in Hawaiian it comes from lu'ana and means "content" or "at ease", a reading that spread after the 1932 film Bird of Paradise gave the name to its island heroine, while in Italy, Portugal and Brazil it is understood as a blend of Luisa and Ana. Its soft sound places it close to Luna and Liana. Luana stood at number 3373 in 2015, peaked at number 1811 in 2023 and ranks 1827 in 2025.
