An acting governor is a person who acts in the role of governor. In Commonwealth jurisdictions where the governor is a vice-regal position, the role of "acting governor" may be filled by a lieutenant governor (as in most Australian states) or an administrator. In some U.S. states, it is a constitutional position created when the governor dies in office or resigns. In other states, the governor may also be declared to be incapacitated and unable to function for various reasons including illness and absence from the state for more than a specified period.
