Delta Sigma Pi () (officially the International Fraternity of Delta Sigma Pi, Inc.) is a coeducational professional business fraternity and one of the largest in the United States. Delta Sigma Pi was founded on November 7, 1907, at the School of Commerce, Accounts and Finance of New York University (NYU) in New York, New York and is currently headquartered in Oxford, Ohio. The Fraternity has 224 active collegiate chapters, 1 startup group, 55 franchised alumni chapters, and over 300,000 initiated members.
Delta Sigma Pi was established to foster the study of business at the university level. Its goals include:
- to encourage social activity among business students,
- to build relationships with the commercial world,
- to promote strong ethical standards, and
- to enhance the civic and commercial welfare of the community.
After rapid expansion in the early 1920s, the fraternity opened its national headquarters in Chicago, Illinois in 1924. In 1957, the central office moved to Oxford, Ohio adjacent to the campus of Miami University.
In 1911 the fraternity published its first newsletter, which soon would be named The Deltasig.
