Triangle Fraternity is dedicated to building better men, better leaders, and better scholars. We are a social organization composed of men within the fields of Engineering, Architecture, and Science.

Triangle Fraternity originated as a social organization for civil engineers in 1907 at University of Illinois Urbana-Champaign. The organization then joined with a similarly minded organization at Purdue to create TriangleFraternity as a national organization. The third chapter to join was located at The Ohio State University in 1911. The Ohio State Chapter has been on campus continually since then.
