Phi Kappa Sigma is an American men's general collegiate fraternity. Following is a List of chapters of Phi Kappa Sigma. In the first decades, several names from the first series of chapter names were re-used. This occurred after cessation of school operations as a result of the Civil War, or after a period of long chapter dormancy, and does not appear to be a continuing practice. Active chapters noted in bold. Inactive chapters and any dormant institutions are in italics.
