The Zeta Psi Fraternity of North America (ΖΨ) was founded June 1, 1847 as a social college fraternity. The organization now comprises about fifty active chapters and twenty-five inactive chapters, encompassing roughly twenty thousand brothers, and is a founding member of the North-American Interfraternity Conference. It has historically been selective about the campuses at which it establishes chapters, focusing on forging new territory and maintaining a presence at prestigious institutions.

Get the Zeta Psi mug.
The 11th oldest fraternity in the world established in 1847. They're highly selective with only 4,000 actives and 55,000 brothers worldwide as of 2019. They can only be found at top tier universities. They were the first fraternity to create install chapters in both Canada and the UK.

They have a rep of being athletic business and poli-sci students. This tends to attract snobby dudes.
It took me two years to finally get a bid into Zeta Psi. I can't mess this up!
