A gay icon is a public figure (historical or present) who is embraced by many within lesbian, gay, bisexual and transgender (LGBT) communities.

Some of the main qualities of a gay icon often include glamour, flamboyance, strength through adversity, and androgyny in presentation. Such icons can be of any sexual orientation or gender; if LGBT, they can be out or not. Although most gay icons have given their support to LGBT social movements, some have expressed opposition, advocating against a perceived "homosexual agenda".
