Meaning and history
Íris means “rainbow” in Greek. It was the name of the Greek goddess of the rainbow, who also served as a messenger of the gods, and it may also refer to the iris flower or the colored part of the eye, both from the same Greek root.
Iris has risen sharply in the modern US rankings, moving from #414 in 2000 to #61 in 2025. It now stands at #61 for girls. That year also produced its highest recorded birth count, at 3,729.
