The Syracuse Triad is the name given to the three women's sororities founded at Syracuse University in the USA. Alpha Phi was founded in 1872 by 10 of the first 20 women admitted into the university. Gamma Phi Beta was founded in 1874 and with it came the term "sorority", which was coined for it at the time of its founding. (Prior to that, women's Greek-letter organizations used the term "women's fraternity", since no more appropriate term existed.) Alpha Gamma Delta completed the triad in 1904.
The three sororities maintain social bonds. Special Syracuse Triad ceremonies or events are held on most campuses where all three groups are present. Examples of common events include Triad Teas or Triad Dances.
