Chi Phi is a collegiate social fraternity. The modern men's collegiate fraternity, Chi Phi's United Order formed from the merger of several previous organizations that had formed independently but were each known as Chi Phi. The first fraternity was established at Princeton University in 1824. As further explained in the main article, Chi Phi came from the following branches:
