Kappa Kappa Psi

Kappa Kappa Psi National Honorary Band Fraternity (ΚΚΨ, colloquially referred to as KKPsi) is an honorary fraternity for college and university band members in the United States. It was founded on November 27, 1919, on Thanksgiving Day, at Oklahoma Agricultural and Mechanical College, now known as Oklahoma State University, in Stillwater, Oklahoma.

Kappa Kappa Psi primarily operates as a recognition society providing service, leadership opportunities, and social programming for band members. The organization is led by the National Council and Board of Trustees, which are supported by the National Headquarters staff. Tau Beta Sigma, National Honorary Band Sorority, has been recognized as a sister organization since 1947, and the two organizations share National Headquarters in Stillwater Santa Fe Depot, a converted historical Santa Fe rail depot that was purchased by the fraternity and sorority in 1991.

Since 1919, more than 66,000 men and women have been initiated into Kappa Kappa Psi, with nearly 6,000 collegiate members active today. Members of Kappa Kappa Psi include President Bill Clinton; chancellor and eleventh president of Indiana University, Herman B Wells; composers John Williams and John Philip Sousa; conductor William Revelli; and jazz pianist and bandleader Count Basie.
