'''Delta Upsilon''' ('''{{lang|grc|ΔΥ}}'''), commonly known as '''DU''', is a collegiate men's fraternity founded on November 4, 1834, at [[Williams College]] in [[Williamstown, Massachusetts]]. It is the sixth-oldest, all-male, college Greek-letter organization founded in North America (only [[Kappa Alpha Society]], [[Sigma Phi]], [[Delta Phi]], [[Alpha Delta Phi]], and [[Psi Upsilon]] predate).<ref name="The Cornerstone">{{cite book|title=The Cornerstone: Delta Upsilon's Guide to College and Beyond|date=2010|publisher=Delta Upsilon Fraternity|location=Indianapolis, Indiana|page=16|edition=25th|ref=1}}</ref> It is popularly and informally known as "DU" or "Delta U" and its members are called "DUs".

In 2018, the fraternity adopted policies to reduce risk.  As of August 1, 2018, hard alcohol was banned from all chapter houses.  As of August 1, 2020, chapter houses must be "substance free" (including wine, beer, and drugs), except for chapters that obtained waivers through 2022, based upon good behavior.<ref>{{cite web|url=https://www.deltau.org/substance-free|title=Substance-Free Housing|access-date=2020-07-01}}</ref>
