What is the mayor of Essex county?

Essex County does not have a single mayor, as it is a county in New Jersey that encompasses multiple municipalities, each with its own mayor. The county government is led by an Executive and a Board of County Commissioners. The current Essex County Executive is Joseph N. DiVincenzo Jr., who has held the position since 2003. Each municipality, such as Newark or Montclair, has its own elected mayor responsible for local governance.
