Delta Upsilon, an international men’s fraternity founded in 1834, is committed to Building Better Men through our four founding principles:

Promotion of Friendship
Development of Character
Diffusion of Liberal Culture
Advancement of Justice

Our Brothers are challenged to live up to these ideals and expect nothing less than excellence from themselves and others.

We are 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.
