List of Phi Sigma Kappa chapters

Phi Sigma Kappa is a men's social and academic fraternity with approximately 74 active chapters and provisional chapters in North America.

Naming rules
Interest groups are named temporarily after the school. Where the fraternity has previously had a presence, re-established groups may refer to themselves by their original chapter name, with the word "Provisional Chapter" appended. Provisional chapters at schools where Phi Sig has not had a presence will be awarded a chapter name as their induction ceremony is scheduled. Where there is a lack of progress or low membership, unsuccessful provisional chapters may be disbanded before receiving a charter or series name.

The 1985 merger resulted in the following naming compromises:
 * In cases where an original Phi Sigma Kappa chapter, as well as a Phi Sigma Epsilon chapter, were present on campus but where both are now dormant, the designation of any new group would normally be the name of the older original chapter, with allowances based on alumni preference. See also the main section on Naming System.
 * Phi Sigma Epsilon's practice was to name interest groups and colonies immediately. Because some colonies earned their charter within months, and others took up to four years, this resulted in a chapter roster that wasn't strictly alphabetical when listed by date of founding. The roster today, and this page, is maintained by chartering date, following Phi Sigma Kappa's practice. Buttons on the header field allow readers to sort by state, school, status, etc.
 * Occasionally, a PSE colony was allowed a name that referenced a former local fraternity's original name: Shepherd College's Sigma Chi chapter of Phi Sigma Kappa, for example, which honors their former local name Theta Sigma Chi.
 * Several Sigma-series names were never assigned, and there are no plans to use them.
