The governor of New Jersey is the head of government of New Jersey. The office of governor is an elected position with a four-year term. There is a two consecutive term term limit, with no limitation on non-consecutive terms. The official residence of the governor is Drumthwacket, a mansion located in Princeton, New Jersey. The governor’s office is located inside of the New Jersey State House in Trenton, making New Jersey notable as the executive’s office is located in the same building as the legislature. New Jersey is also notable for being one of the few states in which the governor’s official residence is not located in the state capital.

The lieutenant governor of New Jersey is an elected constitutional officer in the executive branch of the state government of New Jersey in the United States. The lieutenant governor is the second highest-ranking official in the state government and is elected concurrently on a ticket with the governor for a four-year term. The position itself does not carry any powers or duties other than to be next in the order of succession, but the state constitution requires that the lieutenant governor also be appointed to serve as the head of a cabinet-level department or administrative agency within the governor's administration, other than the position of Attorney General.
