A viceroy /ˈvaɪs.rɔɪ/ is a regal official who runs a country, colony, city, province, or sub-national state, in the name of and as the representative of the monarch of the territory. The term derives from the Latin prefix vice-, meaning "in the place of" and the French word roi, meaning "king". A viceroy's territory may be called a viceroyalty, though this term is not always applied.
