Kappa Alpha Psi (KAΨ) Fraternity, is the second oldest active African American collegiate greek-letter fraternity and since 1911 has been open to men of all races, religion and creed. The fraternity has over 105,000 members with 600 undergraduate and alumni chapters in every state of the United States, with international chapters in the United Kingdom, Germany, Korea, Japan, and the West Indies.

Chartered and incorporated originally under the laws of the State of Indiana as Kappa Alpha Nu on May 15, 1911, the name was changed to KAPPA ALPHA PSI on a resolution offered and adopted at the Grand Chapter in December 1914. This change became effective April 15, 1915, on a proclamation by the then Grand Polemarch, Elder Watson Diggs. Thus, the name acquired a distinctive Greek letter symbol and KAPPA ALPHA PSI thereby became a Greek letter Fraternity in every sense of the designation.

The fraternity has many notable member recognized as leaders in the arts, athletics, business, civil rights, education, government, and science sectors at the local, national and international level.

The fraternity is know for it's "cane stepping" in NPHC organized step shows. Kappa Alpha Psi was the first NPHC member to be incorporated as a national fraternity.
