The Professional Fraternity Association (PFA) is an American association of national, collegiate, professional fraternities and sororities that was formed in 1978. Since PFA groups are discipline-specific, members join while pursuing graduate degrees as well as undergraduate degrees. PFA groups seek to develop their members professionally in addition to the social development commonly associated with Panhellenic fraternities. Membership requirements of the PFA are broad enough to include groups that do not recruit new members from a single professional discipline. The PFA has welcomed service and honor fraternities as members; however, Greek letter honor societies more commonly belong to the Association of College Honor Societies.
