The Sigma Phi Society (ΣΦ) was founded in 1827 at Union College. It was the second Greek fraternal organization founded in the United States and the first to establish a chapter at another college, making it the first national Greek organization.[1] Sigma Phi is a member of the North American Interfraternity Conference.


The Sigma Phi Society (ΣΦ) was founded on March 4, 1827, on the campus of Union College as a part of the Union Triad in Schenectady, New York. Its founders were Samuel W. Beall, Thomas Fielder Bowie, Rev. R. H. Chapman, Hon. Charles T. Cromwell, George N, Porter, and Hon. Charles N. Rowley.[2]

The Alpha chapter of Sigma Phi at Union College has been in continuous operation since its founding, making it the oldest continuously running fraternity chapter in the United States.[3]

In 1831, Beta of New York was established at Hamilton College, making the society the first Greek fraternal organization in the United States to establish a chapter at another college. Thus, Sigma Phi Society is the first National Greek Organization in the United States.

The practices and rituals of the Sigma Phi Society are relatively unknown due to its establishment, and continued consideration, as a secret society.[1]

Sigma Phi is a member of the North American Interfraternity Conference.


The Sigma Phi badge is a monogram with a jeweled Σ directly over a Φ that is either plain or chased.[2] It was designed by Charles N. Rowley, founder of the Beta of New York chapter.[4] In 1879, Baird's stated that the badge was royal purple.[2]
