The men of the Omega Chapter of Sigma Chi at Northwestern University would like to thank you for visiting our website. The Omega Chapter was founded in 1869 at Northwestern, and was rechartered in September 2026, after over 18 months as the Nu Associate Chapter. Omega Chapter Brothers have been involved in campus leadership, academic excellence, and community service for over 150 years. During that time, over 2,500 Northwestern students have expanded their college experience through their membership in Sigma Chi. Sigs are involved in every aspect of campus life, from business fraternities to theatre, and from sports to religious groups. Our Chapter believes in the Spirit of Sigma Chi, which states that “different temperaments, talents, and convictions” are key to any organization’s success. We invite you to explore our website and see if Sigma Chi could be a good fit for you.
