Delta Upsilon, an international men's fraternity founded in 1834, is committed to building better men through four founding principles: the Development of Character, the Diffusion of Liberal Culture, the Promotion of Friendship, and the Advancement of Justice. Through these four principles, our members are challenged 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. We proudly hold the ideal of non-secrecy.

Delta Upsilon has more than 80 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.
