First selectmen is a term used to refer to the chief administrative officers in some municipalities in the United States. Other terms used interchangeably with the first selectmen are town selectmen, town supervisors, and township commissioners. They are responsible for managing the day-to-day operations of small towns and rural communities, including overseeing public services, law enforcement, and government activities. The chief executive officer of a city is sometimes known as the mayor, while counties have a board of supervisors or a county executive, depending on the state. Regardless of the title, the primary goal of these officials is to ensure that their community is governed effectively.
