Founded in 1918, Upsilon Sigma Phi (ΥΣΦ) is the oldest fraternity in Asia.
Based in the University of the Philippines, it has had an unbroken and singular association with the premier state university.
It currently has two chapters — a combined UP Diliman/UP Manila chapter and a second one in UP Los Banos.
From the start and through its 100 years of existence, Upsilonians took it upon themselves to continue the tradition of excellence and leadership that the university was founded on.
Celebrating its 100th year, the members of Upsilon Sigma Phi honor its long history and look forward to upholding its legacy by continuing to scatter its light to the nation.
