History & Origin

Izaiah is a variant spelling of Isaiah, from the Hebrew Yeshayahu meaning 'Yahweh saves.' The prophet Isaiah is the author of the Book of Isaiah in the Old Testament, a text of profound influence on Jewish, Christian, and Islamic theology alike.

Isaiah has been in the U.S. top 100 since the 1990s. The alternate spelling Izaiah follows a well-established pattern of adding a leading vowel (as in Izabella vs. Isabella) to create a fresh look while retaining the original sound. It appeals to parents who want the biblical weight of Isaiah with a distinctive written form.

Did you know? Isaiah is considered the greatest of the Hebrew prophets and authored what is sometimes called the 'Fifth Gospel' — his book contains some of the most direct Messianic prophecies in the Hebrew Bible, including the passage 'For to us a child is born.'
