A county executive is the elected head of government of a county in the United States.
The title for a person holding this position varies depending on the state. Many states with county executives refer to the position as "county executive," but common alternative titles include "county mayor," "county judge," "county judge-executive," "county chair," "chief executive officer," or, in New York, "borough president." In consolidated city-counties, the executive may be referred to as the "mayor" of the city. For example, the "Mayor of San Francisco" technically serves as the mayor of the city and county of San Francisco.
