Kappa Alpha Order (ΚΑ), commonly known as Kappa Alpha, KA, or simply The Order, is an American social fraternity founded in 1865 at Washington and Lee University in Lexington, Virginia. Along with Alpha Tau Omega and Sigma Nu, the order constitutes the Lexington Triad, a trio of now national fraternities formed at the same institution in the same era. Kappa Alpha initially spread in the Southern United States but later added chapters elsewhere in the United States.
