Fraternity and Sorority Affairs

Welcome to the CSU, Chico Fraternity and Sorority Affairs website! Here you will be able to find out all about what it means to be Greek at Chico State. Currently, we have 26 healthy fraternities and sororities that make up our Greek community, which makes up approximately 12 percent of the student population. Greek life membership provides students with opportunities for lifelong friendship, leadership development, scholarship enhancement, philanthropic endeavors, and community involvement. Membership also provides many opportunities for social interactions, such a participating in Greek Week, Omega Week, and the many social events hosted by our chapters. 


Thinking about joining a fraternity or sorority? Still not sure if Greek life is for you? Don't worry! Recruitment is a great way for our campus community to get to know our recognized fraternities and sororities! Joining a fraternity or sorority is a commitment, and we are dedicated to helping you find your home away from home. For fall and spring recruitment schedules, contact us at

Unrecognized Greek-Lettered Organizations

There are a number of organizations in the community that may portray themselves as university-affiliated fraternities or sororities. The chapters below are not associated with the University and have not shown interest in beginning the process of affiliation. Although these organizations may have houses with Greek letters on them, they are not recognized fraternities or sororities. For the safety of our students and the community, we urge you to take caution when associating with these organizations and their events.
