Nessiah is a modern American coinage that borrows the ending of biblical names like Josiah and Messiah, "anointed one", and gives it a fresh N- opening; it has no traditional meaning of its own. It belongs to the recent wave of -iah names for boys. Nessiah had fewer than five births in 2000, broke out of the deep ranks around 2021, peaked at number 2372 in 2022 and sits at number 2669 in 2025 with 49 boys.
