Delta Upsilon is the world’s oldest non-secret, non-hazing fraternity. We believe that if we want our brothers to live our mission of Building Better Men and by our founding values and principles, why would we keep any of that a secret? In Delta Upsilon, you are able to tell the world exactly what your membership means, then prove it through your actions.
DU has officially returned to University of Delaware and Washington State University.
On Nov. 4, 2021, Delta Upsilon celebrates its 187th Founders Day.
