Delta Upsilon

Established on November 4, 1834, Delta Upsilon is the sixth oldest men’s college fraternity. Founded at Williams College in Williamstown, Massachussetts, Delta Upsilon now encompasses over 80 chapters in the U.S. and Canada. Delta Upsilon was the first non-secret and non-hazing fraternity in existence.

Delta Upsilon, an international men’s fraternity founded in 1834, is committed to building better men through four founding principles that challenge our members to expect nothing less than excellence from themselves and others.

There are no secrets with Delta Upsilon. No secret rituals. No secret oaths. We’re proud of what DU stands for. And proud to be the world’s only international fraternity committed to sharing our ideals, symbols, and rituals openly.

Delta Upsilon has more than 85 chapters and colonies in the United States and Canada. More than 110,000 men have been initiated into our brotherhood since our founding. Our members include men from all walks of life and each has been admitted solely on the basis of merit, nothing more, nothing less.
