List of Phi Kappa Psi chapters

Phi Kappa Psi, also called "Phi Psi," is an American collegiate social fraternity founded at Jefferson College in Canonsburg, Pennsylvania on February 19, 1852.

When Phi Kappa Psi is extending to an institution that does not currently have a chapter, a probationary group called a "colony" is formed.

The chapter naming convention is composed of the top-level subnational division of that chapter's host institution, and a Greek letter in alphabetical order from when the charter was originally issued.

For example, the first Phi Psi chapter is from Jefferson College in Canonsburg, Pennsylvania.

As a result, there have been rare instances when the chapter naming convention may not appear to be consistent with the charter dates.
