Welcome to the website for the Chi Phi Fraternity at Oregon State University

The Chi Phi (ΧΦ) fraternity is an American college social fraternity founded in 1824 at Princeton University, in 1858 at the University of North Carolina, and in 1860 at Hobart College, making it the oldest social collegiate fraternity in history. Today, Chi Phi has over 40,000 living alumni members from over 90 active and inactive Chapters.

Greek life is a fantastic way to make the most of your time at college. Greek men are some of the busiest on campus, whether spending time with the brotherhood, participating in one of the many Greek philanthropies, or just studying with friends, there is always something to do as a fraternity man. As you may know, the Greek community at Oregon State was the winner of the Legacy award which is given every three years to the most outstanding Greek community on the west coast.
