Triad (American fraternities)

The term Triad is used to designate a grouping of three national college fraternities or sororities that were founded at the same place. The most famous and oldest triad is the Union Triad at Union College in Schenectady, New York which includes some of the oldest national fraternities still in existence. The second triad that formed is the Miami Triad at Miami University in Oxford, Ohio. There is also the Syracuse Triad at Syracuse University in Syracuse, New York and the Lexington Triad in Lexington, Virginia.

There are also groupings of two fraternities that were established at the same place that are called Duos, including the Monmouth Duo at Monmouth College in Monmouth, Illinois and the Jefferson Duo at Jefferson College in Canonsburg, Pennsylvania.
