Established in 1851, Alpha Delta Pi is committed to sisterhood, values and ethics, high academic standards and social responsibility.

Our founders formed The Adelphean Society for Òthe mental, moral, social, and domestic improvement of its membersÓ at Wesleyan College, the first college in the world chartered to grant degrees to women. The Adelphean Society, later renamed Alpha Delta Pi, is the mother of the modern sorority.

The principles of scholarship, leadership, sisterhood, and service guide over 260,000 women in 161 active collegiate chapters and over 150 alumnae associations of Alpha Delta Pi.

Alpha Delta Pi. First. Finest. Forever. Since 1851.
