Phi Psi (ΦΨ) is an American professional fraternity in the field of textiles and manufacturing engineering.

[1] Members from Alpha chapter began a search for a national social fraternity to join.

In what appears to be a friendly schism, a majority or all of its members formed a separate organization from Phi Psi on November 14, 1964 when they were accepted as the Pennsylvania Omicron chapter of Sigma Phi Epsilon.

Yet the Alpha chapter of Phi Psi continued independently on the campus, remaining active today.
