Alpha Delta Pi is the world's oldest secret society for collegiate women. Originally named The Adelphean Society, it was chartered by Eugenia Tucker Fitzgerald at Wesleyan College in Macon, Georgia in 1851. Since then, the Alpha Delta Pi Sorority has flourished into an international organization with 155 active chapters, and its founding principles of scholarship, leadership, sisterhood, and service continue to guide both collegiate members and alumnae. Our sisters are honored to be a part of this long and rich heritage.
