Phi Gamma Delta (also known as FIJI and Phi Gam) is a social fraternity with more than 142 active chapters and 13 colonies across the United States and Canada. It was founded at Jefferson College, Pennsylvania, in 1848. Along with Phi Kappa Psi, Phi Gamma Delta forms a half of the Jefferson Duo. Since its founding in 1848, the fraternity has initiated more than 170,000 brothers. The nickname FIJI is used commonly by the fraternity due to Phi Gamma Delta bylaws that limit the use of the Greek letters.
