The Marriage Equality Act passed the Assembly 80-63.
It would grant same-sex couples equal rights to marry "as well as hundreds of rights, benefits and protections that are currently limited to married couples of the opposite sex," according to Gov. Andrew Cuomo's office.
"This is an immense step toward achieving true equality for all here in New York," said Democratic Assemblyman Daniel O'Donnell, who argued that he and his partner should be allowed to marry.
Wednesday night's debate included discussion of religious, traditions, customs and families. Small gay rights flags decorated many desks in the chamber.
Same-sex marriage is a fundamental human right, said Democratic Assemblyman Richard Gottfried during the debate.
