Phi Kappa Phi National Organization
Founded in 1897 at the University of Maine, Phi Kappa Phi is the nation's oldest and most selective collegiate honor society for all academic disciplines. Its chapters are on more than 300 campuses in the United States and the Philippines. Each year, approximately 30,000 members are initiated.
Since its founding, Phi Kappa Phi has initiated more than 1.25 million members into its ranks; all of these members have received emblems and certificates of membership. However, Phi Kappa Phi is much more than an emblem and a line on a résumé. It is a global network comprised of the best and brightest from all academic disciplines - a community of scholars and professionals building an enduring legacy for future generations.
