Miko is a short form of Michael used in Finland, Hungary and parts of Eastern Europe, so it carries the Hebrew meaning "who is like God?". In Japanese the same syllables are a word for a shrine maiden, which gives the name a second, unrelated life as a girls' name. For boys in the United States Miko is rare; it peaked at number 1981 in 2023 and ranks number 2743 in 2025 with 47 births.
