The Alpha Delta Phi Society is a self-governing, coeducational organization dedicated to cultivating character, scholarship, and enduring friendships. With eight active chapters and four affiliates, our literary society is one of North America’s foremost coeducational Greek-letter institutions. Our literary tradition fosters life-long intellectual growth, mentoring, and achievement among our members. The Alpha Delta Phi was founded by Samuel Eells in 1832 to encourage free thought and to supplement a rigid classroom education.

The Alpha Delta Phi Society, formed by a group of chapters that withdrew from the Alpha Delta Phi Fraternity in 1992, is an independent and legally separate gender-inclusive organization not affiliated with the Fraternity.


“[Alpha Delta Phi] must be built on a more comprehensive scale than other societies, in regard to its intellectual proportions; providing for every variety of taste and talent, and embracing every department of literature and science.”
—Samuel Eells, founder of Alpha Delta Phi, 1832
