Micaiah is a Hebrew name that means "who is like Yahweh?", a longer form of Micah. In the Old Testament the prophet Micaiah is the lone voice who tells King Ahab the truth about his coming defeat. The name appeals to parents who like Josiah and Isaiah but want something rarer. In the United States Micaiah has never reached the top 1000; it peaked at number 1274 in 2001 and stands at number 1386 in 2025.
