Alpha Phi Delta (ΑΦΔ), commonly referred to as APD, is a Greek social fraternity that evolved from an exclusive Italian society (Il Circolo Italiano) at Syracuse University in 1914. There were seven founding members who strove to create a brotherhood that would last long after their college days. Soon after founding, Alpha Phi Delta spread from Syracuse and became a National Fraternity. Alpha Phi Delta is traditionally an Italian-American heritage Fraternity; however, since September 2, 1965 it has welcomed young men of all racial backgrounds.
The fraternity has more than 20,000 lifelong members.
Alpha Phi Delta is also the top represented fraternity in the New York City Tri-State Area, and among the top on the East coast.
