A charter township is a form of local government in the U.S. state of Michigan. Townships in Michigan are organized governments. A charter township has been granted a charter, which allows it certain rights and responsibilities of home rule that are generally intermediate between those of a city (a semi-autonomous jurisdiction in Michigan) and a village. Unless it is a home-rule village, a village is subject to the authority of any township in which it is located.
