The Constitution of the State of Connecticut is the basic governing document of the U.S. state of Connecticut. It was approved by referendum on December 14, 1965, and proclaimed by the governor as adopted on December 30. It comprises 14 articles and has been amended 31 times.

This constitution replaced the earlier constitution of 1818. It is the state's second constitution since the establishment of the United States. An earlier constitution dating from colonial times, the Fundamental Orders of Connecticut, remained the basis of government even as Connecticut gained its independence from Great Britain, existed as an independent polity, and joined the United States.

Amending the constitution 
Legislature and referendum
The Connecticut constitution can be amended via a process that originates in the General Assembly. If a joint resolution proposing a constitutional amendment passes each house of the General Assembly with a three-fourths majority of the votes cast, the amendment is submitted to the voters in the next even-numbered year's general election. If such a joint resolution fails to win a three-fourths majority vote in either house but still obtains a majority, it must receive a majority in each house during the next legislative session before being submitted to the voters in the next even-numbered year's general election. An amendment that wins a majority of the votes cast in the referendum is adopted.

Constitutional convention
A constitutional convention can amend the constitution. Such a convention is called either:
 when called for by a two-thirds vote of each house of the General Assembly, provided at least 10 years have passed since a constitutional convention was convened; or
 when approved by a majority vote of the electorate, to whom the question "Shall there be a Constitutional Convention to amend or revise the Constitution of the State?" is submitted whenever 20 years have passed since a constitutional convention was convened and since the question of calling a convention was submitted to the voters.

The General Assembly shall decide, by a two-thirds vote of each house, the method for selecting convention delegates and the date of the convention's convening and adjournment. The most recent referendum on calling a constitutional convention was held on November 4, 2008. Voters opposed calling a constitutional convention by a vote of 847,518 to 579,904.

Earlier Connecticut constitutions 

The Fundamental Orders of Connecticut (1638) is considered by many to be the state's first constitution, although it was adopted while the state was still an English colony. The document recognized no allegiance to England but instead an independent government. The Charter of the Colony of Connecticut (1662) officially superseded the Fundamental Orders, but the local government continued operating under the previous rules. Even after the American Revolutionary War, the state retained its constitution for another 40 years.

The colonial charter was abolished with the adoption of the first state constitution in 1818. In contrast to the Fundamental Orders, that constitution provided for freedom of religion.

On October 1, 1901, Connecticut residents voted nearly 2-to-1 in favor of calling of a constitutional convention to revise the constitution. A convention was held, and a revised constitution was proposed. On June 16, 1902, voters rejected the revised constitution by a margin of more than 2-to-1.
