Founded on Nov. 4, 1834, at Williams College, Delta Upsilon is the sixth oldest men’s college fraternity and the first to be founded as non-secret. Delta Upsilon is not your typical fraternity. Our non-secret heritage and our dedication to creating a modern fraternity experience help us in Building Better Men. Fraternity membership is one of the most valuable extra-curricular experiences available to college men. What makes Delta Upsilon different from the rest? While our mission and vision remain true to our founding purpose, we are not stuck in the past. Our aim is to provide a modern fraternity experience that creates men of character no matter the era.
