Amariah is a Hebrew name from the Old Testament that means "God has said" or "promised by God", borne by several priests and officials of the kingdom of Judah. Although biblical Amariah was a man, the soft -iah ending has made it a girls' name in modern America, in step with Zariah and Azariah. For girls Amariah has risen from number 2942 in 2000 to number 1152 in 2025, its highest rank so far.
