# List of social fraternities

Social, collegiate, or general fraternities in the North American fraternity system are those that do not promote a particular profession, as professional fraternities do, or discipline, such as service fraternities. Instead, their primary purposes are often stated as the development of character, literary or leadership ability, or to serve a more simple social purpose.
A fraternity is usually understood to mean a social organization composed only of men while a sorority is composed of women. However, many women's organizations and co-ed organizations refer to themselves as women's fraternities.
This list of collegiate North American fraternities is not exhaustive. It consists only of social collegiate fraternities; other types of social fraternal organizations can be found under the list of general fraternities. Cultural interest groups can be found under cultural interest fraternities and sororities. Women's organizations are listed in List of social sororities and women's fraternities.
Some organizations in this list have a specific major listed as a traditional emphasis. These organizations are social organizations that cater to students in those majors. Other listed fraternities have a traditional emphasis on a specific religion or ethnic background but are primarily social in function.
