The Governor of Connecticut is the head of the executive branch of Connecticut's government and the commander-in-chief of the state's military forces. The governor has a duty to enforce state laws, and the power to either approve or veto bills passed by the Connecticut Legislature and to convene the legislature. Unusual among U.S. governors, the Governor of Connecticut has no power to pardon.

The current Constitution of Connecticut, ratified in 1965, calls for a four-year term for the governor, commencing on the Wednesday after the first Monday in the January following an election. The previous constitution of 1818 originally had only a one-year term for governor; this was increased to two years in 1875, and four years in 1948. The 1875 amendment also set the start date of the term to its current date; before then, it was the first Wednesday in the May following an election. The constitution provides for the election of a lieutenant governor for the same term as the governor. The two offices are elected on the same ticket; this provision was added in 1962. In the event of a vacancy in the office of governor, the lieutenant governor becomes governor. Before the adoption of the 1965 constitution, the lieutenant governor only acted as governor. There is no limit of any kind on the number of terms one may serve.

Connecticut did not create a state constitution for itself until several decades after it became a state; until 1818, the state operated under the provisions of its colonial charter. The charter called for the election of a governor every year, but not more than once every two years, with the term commencing on the second Thursday in May.

There have been 67 governors of the state, serving 71 distinct spans in office. The longest terms in office were in the state's early years, when three governors were elected to ten or more one-year terms. The longest was that of the first governor, Jonathan Trumbull, who served 14+¹⁄₂ years, but 7 of those as colonial governor; the longest-serving state governor—with no other position included in the term—was his son, Jonathan Trumbull, Jr., who served over 11+¹⁄₂ years. The shortest term was that of Hiram Bingham III, who served only one day before resigning to take an elected seat in the U.S. Senate. The current governor is M. Jodi Rell, who took office on July 1, 2004, upon the resignation of John G. Rowland; her term will expire in January 2011.
