ambassadress

An ambassadress is a female official envoy, especially a high-ranking diplomat who represents a state and is usually accredited to another sovereign state or to an international organization as the resident representative of their own government or sovereign or appointed for a special and often temporary diplomatic assignment.[1] The word is also often used more liberally for persons who are known, without national appointment, to represent certain professions, activities and fields of endeavor such as sales. https://en.wikipedia.org/wiki/Ambassador
