Democrat John Carney announced his support for marriage equality Monday on his website.
He said as a Catholic, he has tried to reach a balance between honoring the religious sacrament of marriage and letting same-sex couples to enjoy legal recognition.
Carney said he does not believe that it is right for the government to treat couples differently because of sexual orientation.
Same-sex civil unions are legal in Delaware.
State lawmakers have not yet introduced a bill authorizing same-sex marriage, but plan to do so this year.
