A Lesbian, gay, bisexual, transgender, queer/questioning/Same Gender Loving fraternity or sorority is a Greek Letter Organization which exists for service and fellowship within those communities. It should be noted that the women’s organizations are often (but not always) separated by gender expression, with masculine of center (MOC) women often joining women’s fraternities.
This list does not include non-Greek letter LGBT social clubs, which have their own section.
