   A governor is the head of a non-sovereign state. Countries all over the world have the role of governor within their government, with differing titles for that role.

Each of the 50 states in the United States has a governor, who is ultimately responsible for how the state is run. State constitutions delegate different duties and requirements for the role of governor, such as the number of terms a candidate may be elected for the office and the age requirement to run. The rules for the line of succession vary, as do the responsibilities of the role. There are some significant similarities however.

In all US states, the governor is the chief executive of the state and runs the executive branch of the government. He is the commander-in-chief of the military and is responsible for managing the state budget. Furthermore, the US constitution states that the governor of a state is allowed to fill vacancies in the state's two Senate seats.

In Georgia, for example, the governor has the power to veto legislation from the Georgia General Assembly. The veto, however, can be overturned by two-thirds of both houses in the Assembly: the House of Representatives and the Senate. In addition, the governor can fill vacancies in both Assembly houses.
