Kappa Kappa Psi, National Honorary Band Fraternity (, colloquially referred to as KKPsi or KKY) is a fraternity for college and university band members. It was founded on November 27, 1919 at Oklahoma Agricultural and Mechanical College in Stillwater, Oklahoma. Kappa Kappa Psi primarily operates as a recognition society providing service, leadership opportunities, and social programming for band members. 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 Station, 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.
