This is a list of LGBT and LGBT-friendly fraternities and sororities. Another type of LGBT-affirmative campus organization (beside Gay-Straight Alliances and LGBT student centers), LGBT fraternities and sororities have existed since the 1980s, with Delta Phi Upsilon being established in 1985 and Delta Lambda Phi being established 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 intrafraternal homophobia by longer-established organizations. This is not an exhaustive list and only includes organizations with a current wikipedia page.
Organizations for women
- Alpha Lambda Zeta – fraternity for women who identify as aggressive lesbians
- Alpha Pi Delta Sorority, Inc – sorority for feminine lesbian women
- Gamma Rho Lambda — sorority for women, transmen and non-binary students of any race or sexual orientation
- Kappa Alpha Lambda – sorority for feminine lesbian women
- Omicron Epsilon Pi — sorority for lesbians, particularly of color
Organizations for men

Organizations for all genders
- Theta Pi Sigma - queer gender-neutral frarority at the University of California, Santa Cruz. The organization was forced to change their name from Delta Lambda Psi to Theta Pi Sigma due to a lawsuit with Delta Lambda Phi.

- Sigma Omicron Rho - gender-inclusive queer and ally fraternity at the University of Virginia, main campus. Founded in 2009. 
- Phi Sigma Pi (ΦΣΠ) is a national Gender-inclusive honor fraternity based in the United States. The fraternity is a 501(c)(3) not-for-profit organization incorporated in the state of Pennsylvania, with the purpose of fostering the ideals of scholarship, leadership and fellowship. Phi Sigma Pi is organized into approximately one hundred collegiate chapters at four-year collegiate institutions and several regionally established alumni chapters and associations serving approximately 40,000 brothers. Although collegiate chapters may fall under the purview of university student governing bodies, Phi Sigma Pi maintains no affiliation with the North-American Interfraternity Conference.
