Same-sex marriage in Connecticut

Same-sex marriage has been legally recognized in Connecticut since November 12, 2008 as a result of the Connecticut Supreme Court ruling 4–3 in Kerrigan v. Commissioner of Public Health that the state's statutory prohibition on same-sex marriage violated the Constitution of Connecticut and that the state's civil unions failed to provide same-sex couples with rights and privileges equivalent to those of marriage.

Connecticut was the second U.S. state to legalize same-sex marriage after neighboring Massachusetts. In 2009, the Connecticut General Assembly repealed the statutory prohibition on same-sex marriage, and in October 2010 it ended the ability to enter into civil unions.
