Alpha Delta Phi (ΑΔΦ; commonly known as Alpha Delt, AD, ADPhi, A-Delt, or ADP) is a North American Greek-letter social college fraternity. Alpha Delta Phi was originally founded as a literary society by Samuel Eells in 1832 at Hamilton College in Clinton, New York. Its more than 50,000 alumni include former presidents and senators of the United States, and justices of the Supreme Court.
The mission of the Alpha Delta Phi Fraternity is to provide a comprehensive and positive personal growth experience for all undergraduate and alumni brothers: social, ethical, leadership, scholastic, community service, and literary.
