The Governor of the Commonwealth of Massachusetts is the executive magistrate of the Commonwealth of Massachusetts, United States. The current governor is Democrat Deval Patrick. The next election will be 2014.

Part the Second, Chapter II, Section I, Article I of the Massachusetts Constitution reads,

The Governor of Massachusetts is the chief executive of the Commonwealth, and is supported by a number of subordinate officers. He, like most other state officers, senators, and representatives, was originally elected annually. In 1918 this was changed to a two-year term, and since 1966 the office of governor has carried a four-year term. The Governor of Massachusetts does not receive a palace, other official residence, or housing allowance. Instead, he resides in his own private residence. The title "His Excellency" is a throwback to the royally-appointed governors of the Province of Massachusetts Bay. The first governor to use the title was Richard Coote, 1st Earl of Bellomont in 1699; since he was an Earl, it was thought proper to call him "Your Excellency." The title was retained until 1742, when an order from King George II forbade its further use. However, the framers of the state constitution revived it because they found it fitting to dignify the governor with this title.

Massachusetts (ⁱ/ˌmæsəˈtʃuːsɨts/), officially the Commonwealth of Massachusetts, is a U.S. state in the New England region of the northeastern United States of America. It is bordered by Rhode Island and Connecticut to the south, New York to the west, and Vermont and New Hampshire to the north; at its east lies the Atlantic Ocean. Massachusetts is the 7th least extensive, but the 14th most populous and the 3rd most densely populated of the 50 United States. The state features two separate metropolitan areas – the eastern Boston metropolitan area and the western Springfield metropolitan area. Approximately two thirds of the state's population lives in Greater Boston, most of which is either urban or suburban. Western Massachusetts features one urban area – the Knowledge Corridor along the Connecticut River – and a mix of college towns and rural areas. Massachusetts is the most populous of the six New England states and has the US's sixth highest GDP per capita.
