List of social fraternities and sororities

From Wikipedia, the free encyclopedia
Jump to: navigation, search
For other uses, see Fraternity (disambiguation).

Social or general fraternities and sororities, in the North American fraternity system, are those that do not promote a particular profession (as professional fraternities are) or discipline (such as service fraternities and sororities). Instead, their primary purposes are often stated as the development of character, literary or leadership ability, or a more simple social purpose. Some organizations in this list have a specific major listed as a traditional emphasis. These organizations are social organizations which cater to students in those majors. Other organizations listed have a traditional emphasis in a specific religion or ethnic background. Despite this emphasis, most organizations have non-discrimination membership policies.

Fraternity is usually understood to mean a social organization composed only of men, and sorority one of women, although many women's organizations and co-ed organizations also refer to themselves as fraternities. For the purposes of this article, national also includes international organizations, and local refers to organizations that are composed of only one chapter. This list is not exhaustive and does not include local organizations that do not have Wikipedia articles.
