This is a list of LGBT and LGBT-friendly fraternities and sororities. Such groups have existed since the 1980s, with Delta Phi Upsilon being established in 1985 and Delta Lambda Phi in 1986. They are intended to provide members with access to Greek life without fear of homophobic reprisal or behavior by fellow members, resulting from a history of homophobia within longer-established organizations. This is not an exhaustive list.
