The Alpha Delta Phi Fraternity was founded in 1832 at Hamilton College in Clinton, New York by Samuel Eells (1810-1842). Founded as a literary society, it evolved into one of the most distinguished of the original American college fraternities. It has retained its focus on its literary roots, by attracting only the best students at only the more prestigious colleges and universities in Canada and the United States. Our chapters are leaders on their respective campuses, where some of our chapter houses have been designated architectural or historic landmarks. The Alpha Delta Phi experience has helped a disproportionate number of its 50,000 lifelong members to become top leaders in industry, government, education, and religion.

We welcome you whether you are a prospective member, a current Undergraduate Brother, an Alumnus Brother, or just an interested visitor, to explore this uniquely distinguished organization. Here you will find information about the history and traditions of Alpha Delta Phi, about our headquarters office and staff, and about our chapters and their host institutions.
