Zeta Psi (ΖΨ) is a collegiate fraternity.[2] It was founded on June 1, 1847, at New York University. The organization now has 90 chapters, with roughly 70,000 members. Zeta Psi is a founding member of the North American Interfraternity Conference.
As one of the world's oldest collegiate fraternities, Zeta Psi has historically been selective about the campuses at which it establishes chapters.[3] The chapter at the University of California, Berkeley (June 10, 1870) made Zeta Psi the first fraternity in the U.S. west of the Mississippi.[4] Its chapter at the University of Toronto, (March 27, 1879) was the first in Canada.[5] The founding of the Eta chapter at Yale University (1889) briefly made it the only fraternity to have chapters at all eight Ivy League schools.[6] The fraternity became intercontinental on May 3, 2008, with the chartering of Iota Omicron at the University of Oxford, and then with the chartering of Theta Omicron at Trinity College Dublin in 2012. Its newest chapter, Psi Omicron at the University of Paris, joined on May 18, 2019.
The motto is "ΤΚΦ" in Greek, rendered in English as "Tau Kappa Phi", "TKP", or "TKPhi".
Zeta Psi's headquarters is located in Pearl River, New York.
