名人 (míngrén) means "celebrity" or "famous person" in Chinese. It is a compound noun formed from 名 (fame) and 人 (person), used to refer to well-known public figures in any field. You can use it in the same way you would say "celebrity" in English, often paired with modifiers like 国际名人 (international celebrity).
