Sigma Phi Lambda is a nation wide Christian sorority whose purpose is to glorify God and make His name great. We are a sorority that strives to glorify God by providing a source of fellowship for college women who sincerely seek to know His person, His will, and His ways. We are a non-denominational organization of sisters where fellowship with God is fostered by growth in unity with one another. Through weekly meetings that include worship, encouragement, and fellowship, Phi Lamb provides an alternative to Panhellenic sororities. Sigma Phi Lambda is not a Panhellenic sorority.


Phi Lamb was founded in 1988 at the University of Texas at Austin. Our colors are red and white, our symbol is the lamb, and our sorority verse is Romans 15:5-6. We are partnered with World Vision as our philanthropy.
