Izabella is the Polish and Hungarian spelling of Isabella, the medieval Spanish and Italian form of Elizabeth, which means "God is my oath" or "devoted to God". The Z gives the classic name a modern, slightly edgy look that American parents picked up as Isabella climbed to number one. In the United States Izabella ranked number 799 in 2000, peaked at number 138 in 2010 and has since eased to number 564 among girls' names in 2025.
